[mythtv-users] HVR4000 woes

[Liam Friel]

Ah ...

I have updated backend and frontend to the release-0-23-fixes branch and now
things are much better.

DVB-T and DVB-S zapping working fine and stable, using the HVR4000 card.

So now my Ubuntu 9.10 + myth 0-23-fixes is working for me for HVR4000 +
TT-3200 combination.

I have one problem to look into: HD services (BBC HD and ITV1 HD) don't play
nicely, giving me stuttering playback and lots of "NVP: prebuffering
pauses", although my backend system is 91% idle and the frontend is 75%
idle. So I need to dig into that a bit next.

But updating to release-0-23-fixes cured the stability issue.
