Hauppauge WinTV-HVR4000 DVB-S/S2/T/Hybrid no longer works properly with kernel 3.3

[Thomas Steinborn]

Hi,

hope you can point me into the right direction.

I have got 2 Hauppauge WinTV-HVR4000 DVB-S/S2/T/Hybrid cards in my
system. They worked perfectly fine with kernel 3.2 (e.g. the last
Fedora 16 kernel that worked is 3.2.10-3.fc16.x86_64).

As soon as Fedora went kernel 3.3 (kernel 3.3.0-4.fc16.x86_64) the
problems started. The cards are still recognized and you can tune
them. But trying to watch any DVB-S (or DVB-S2) channel just results
in block artefacts, loss of audio-video sychronization etc. The only
thing /var/log/messages or dmesg tells me is:


cx8802_start_dma() Failed. Unsupported value in .mpeg (0x00000001)

Same machine, same everything, just rebooting back into the 3.2 kernel
the problem is gone.

Any idea where I could start my investigation, please?

Thanks
Thomas

I got pointed to:

http://www.spinics.net/lists/linux-media/msg45592.html

Has this been applied to the kernel since?
