Known Problems and Solutions

After installation of the Windows MediaPlayer 9 and/or DirectX 9 the DVBViewer does not function anymore.

The installation deleted important settings of the SkyStar2 card. A new installation of the SkyStar2 card is necessary. Please read the corresponding notes of TechniSat!

I have neither audio nor video.

Maybe there are no A/V decoders installed. You can use this tool to check it.

I have neither audio nor video with the DVBViewer source-filter.

This source-filter needs both PMT and PCR, therefore you must perform a channel-scan. Imported lists seldom feature the needed values. Older channel-lists are not compatible with DVBViewer Pro 3.x, you need to update them.

All channels of the Pro7/Sat1-group (Pro7, Sat1, Kabel1, N24) are distorted, there are packet errors.

A frequent problem. Usually it is caused by a DECT-phone. The base station (!) should be moved as far away as possible from the PC. If it is caused by your neighbour through the wall you will have to move your PC, though.

Only some channels can be received.

The voltage produced by the TV card for driving the LNB may be too low, so it is unable to switch from horizontal polarisation to vertical or back. LNBs of older design or multi-switches without own power supply sometimes have such a high current consumption that the voltage breaks down. You should upgrade to a modern LNB or a multi-switch with external power supply.

You may have also mixed up the cabling from the LNB to the multiswitch.

Another reason may be an old LNB, which is not suitable for digital reception. Thus only channels in the low band can be received; all channels in the high band (with a frequency higher than approximately 11700 MHz) cannot be tuned.

At last there may be a problem with 22 kHz signal used for switching between the low band and the high band. You should check the cabling.

After selecting a channel the error message "Cannot set Tunerstatus (wrong settings), error 9001015" appears.

This simply means, that the channel cannot be tuned. Generally the signal strength will be down to zero, due to one of the following reasons:

  • The values in the channel list are incorrect and have to be adjusted, particularly the frequency, polarisation, symbol rate, LNB selection, LNB frequency (LOF) or DiSEqC (see Editing Channels in chapter 6).

  • The channel moved to another transponder/frequency (which happens quite frequently with digitally broadcast channels), or the broadcasting was terminated. Try to scan the satellite position in order to find it again (see Channel Search in chapter 6)

After switching over to a channel you get neither a picture nor sound, although the signal strength is sufficient. Also the error message "Cannot locate B2C2 MPEG Filter Audio/Video Ctrl. Interface, error 91000101" may appear.

If only one channel is concerned (or few channels), you most probably have selected an encrypted channel. Please have in mind, that some channels are only part of the day not encrypted. If the channel is not encrypted, some of its values in the channel list may be incorrect (particularly the audio or video PID, see Editing Channels in chapter 6)

If all channels are concerned, it may be caused by a crash or a malfunctioning of the drivers. Solution: Terminate all programs which use the SkyStar2 card (DVBViewer, Sky4PC) and disable and re-activate the card via the device manager (windows key + pause). You may also use the FreeLNB-Tool. If this does not work, try to unplug your PC from the power supply for a few seconds, in order to completely reset the SkyStar2 card.

This behaviour was also observed in conjunction with Norton AntiVirus®, which sometimes interrupts the network connections when the SkyStar 2 card is initialized.

In certain cases your SkyStar2 card may have been locked permanently. This is mostly caused by EON® (Europe Online) software. Other reasons for this lock, which possibly occurs in rare cases, have not been investigated yet. If you suspect that your card is locked, first visit the DVBViewer forum and read thoroughly everything concerning the EON lock. Acting without precaution can damage your card permanently. Using some of the "unlocking" patches found at various upload-centers often worsens the problem and you will void your warranty. Ask for help if you are not sure what to do.

The Teletext does not function.

This is frequently due to missing teletext PIDs in the channel list, particularly after the import of TechniSat or SatcoDX channel lists, which do not contain this information. Solution: Input the correct values manually, perform a channel-search or have a look at chapter 6.

When playing MPEG files with the DVBViewer or another media player seeking is not possible.

This problem is caused by the Microsoft MPEG2 demultiplexer filter which is responsible for the separation of the audio and video data. It affects all media-players. Solution: Install the MPEG2 Decoderpack from Elecard - see this this paragraph in chapter 9.

The playback of PVA files recorded with the DVBViewer does not work.

Probably there is no PVA Splitter installed (a filter for separating the video and audio data). Solution: Install the Decoder Package from Elecard.

When installing a TechniSat PCI TV-card there are blue screens with an ASUS A8N SLI (Deluxe).

These boards have a weak power supply for PCI. Therefore powerful PCI-cards are not supported.

The DVBViewer does not output Dolby digital (AC3) over the SPDIF link of the sound card.

Solution: The following steps must be executed:

  • Download and install the Odio Dekoda from or the AC3-Filter 1.01a or newer from Alexander Vigovsky.

  • Select SPDIF in AC3-filter.

  • In the channel list edit the channel, e. g. Pro7 (on Astra 19.2 there are only Pro7, Sat1 and ZDF broadcasting in AC3 (2/0 and 3/2)). Enter 257 for Pro7, 1795 for Sat1 and 125 for ZDF as audio PID and check the AC3 box.

  • Tune the channel and enjoy Dolby digital.

A screenshot of the running show with [PrtScr] just shows a black DVBViewer window.

DVBViewer produces the television or video picture independently of the normal display output in Overlay Mode. Therefore it is not transferred to the windows clipboard. A solution for making screenshots is the installation of the FFDShow filter (see here).

Alternatively you may use the VMR mode, which uses the normal display output.

The adjustments of brightness, contrast and saturation is not possible, or the TV picture does not respond to it.

You have selected "Unchanged" or "VMR" as Render Output. Go to Settings/Options/DirectX/Render Output and change it to "Overlay Mixer". Or use the adjustments provided by your graphics card software.

After switching to another television program the audio is distorted (Mickey Mouse voices).

Have a look at chapter 7 regarding the fast channel switching.

I can't use VMR in combination with the Cyberlink MPEG2-decoder.

The Cyberlink decoder isn't yet compatible with VMR.

The DVBViewer does not shut down the system with Windows 98/ME.

Start RegEdit and search for: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon. Now double-click the entry „PowerdownAfterShutdown“ and set the value to 1.

There are horizontal lines in moving objects (it looks like fringes).

First of all: It's not a bug! This is called "interlace". PAL has 25 frames per second which consists of each 25 upper and 25 lower fields which are not "correctly" integrated (roughly spoken).

Read further for a more detailed description:

Basically each frame is split into two separate pictures, which both are missing half of the picture information. The split is done by the horizontal lines. With PAL resolution you have 576 horizontal lines. For easier understanding the numbering begins from the top of the frame being the line number 1. The frame is being split to half-frame A and half-frame B (also called fields) -- the half-frame A would contain all uneven lines 1, 3, 5, 7, ... and the half-frame B would contain the even horizontal lines 2, 4, 6, 8, 10, ...

With PAL the video has a frame frequency fps) of 25fps, there are 50 fields per second that are being updated. First come the uneven fields which leave the other ones blank. Then come the even fields that fill the missing lines 2, 4, 6, ... and leaves the existing "half A"'s lines showing as well.

Now you have a full frame. Then come the uneven fields of the second frame that overwrite the uneven fields of the first frame, but leave the first frame's even fields. Now you have a mixture of uneven lines of the second frame and even fields of the first frame.

This leads to the “fringing” effect. This is no bug. You can solve this issue by using a video decoder with integrated de-interlacing, for example Mediamatics (bundled with your TechniSat SkyStar 2), NVIDIA® (from NVDVD) or Cyberlink®. This only applies to live watching – the recording is still interlaced. That means, you have to use a de-interlace filter, in VirtualDub for example Donald Grafts "smart deinterlacer", when converting to DiVX®. Some broadcasts are progressive, there is no need for de-interlacing. De-interlacing is also not necessary when creating a DVD.

You should also have a look here: This is a very thorough guide about interlace and de-interlacing. Another site is (very technical).
