Binary package hint: xserver-xorg-video-v4l
Video from analog TV channels is shown distorted by black bars.
DVB video (digital TV) has block artefacts and chopped audio (the latter even occurs on DVB radio channels) whenever accessed by v4l (presumably upgraded to v4l2 in Ubuntu 8.04 "Hardy Heron").
The issue occurs in xawtv (output reproduced below) but can also be demonstrated in other applications such as the Ekiga VoIP client (formerly known as GnomeMeeting) when configured to use the same device as its video feed.
The audio distortion disappears as soon as the video display is closed with the source left running.
This as well as the fact that the same hardware performs just fine under a legacy Ubuntu 7.04 installed in parallel demonstrates that bad signal (i.e. weak TV reception leading to UNCorrectable errors) cannot possibly be the cause of these issues, also the symptoms may look similar at first glance.
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/230882 may be related.
mplayer and xine have no trouble playing back the same streams through other methods, such as streamed over http by a local VDR (a Linux "killer app" which is otherwise rendered unusable by this and a related issue, a conflict of a buggy budget_av kernel module, cf. http://linuxtv.org/hg/v4l-dvb/log/19964051c5f1/linux/drivers/media/dvb/dvb-core/dvb_ca_en50221.c, somehow conflicting with the serial port handling and hence driving system load through the root, cf. http://vdr-portal.de/board/thread.php?threadid=77155 and http://vdr-portal.de/board/thread.php?threadid=77950 in German).
