[mythtvnz] DVB-T recording artefacts after upgrade to Mythbuntu 11.10 with HVR2200

[Aaron Whitehouse]

Hi,

I use a DVB-T Hauppauge HVR-2200 to record FreeviewHD and play back with
VDPAU. All was working fine with Mythbuntu 11.04 and then I upgraded to
11.10. (My first attempt was updating through Update Manager and that
resulted in my system not booting any more, probably to do with some
LightDM setting, but I ended up reinstalling from scratch.)

Since we upgraded, we are getting intermittent strange visual artefacts
in the recordings, where blockiness gets worse until it is bad enough
that minutes of a program will be completely unwatchable and sound is
distorted to the point that we can't understand it.

The new features aren't that compelling, so if nobody has any ideas I'll
just roll it back to the old Clonezilla image of 11.04 (I learnt that
trick a while ago!!!)

Thanks in advance,

Aaron
