[pvrusb2] Can't get Hauppauge HVR-1950 to work

[Lars Maersk]

Greetings,

I have an HVR-1950  75111 LF REV C3E9. I extracted the drivers from the
Version 4.6 CD using http://www.isely.net/downloads/fwextract.pl.

% ls /lib/firmware/v4l*

When I plug the device, dmesg shows:

Except for the "not a valid video input!", I'd think everything is right.

Now my problems:
1. I use mplayer to play both analog and digital. When I issue:
%  mplayer pvr:// -tv
driver=v4l2:input=0:device=/dev/video1:chanlist=us-bcast:channel=10

video and audio work perfectly for about 5 minutes. After that I get this
invariably:

Broken frame at 0xD5B040

Too many video packets in the buffer: (4096 in 7989804 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
