It wasn't entirely tongue in cheek. Channel surfing and liveTV are not
MythTV's strengths. (channel flipping always takes longer than most
STB's or TV built in tuners given the delay inherent in caching
everything to disk and playing back from disk).
If you look through the archives many people are negative about
LiveTV. When you can record what you want to watch and watch it when
you want to do so, why be constrained at all by the networks'
timetable. Plus if you watch a recorded stream you can flick through
the ads, and end up spending 45 minutes watching an hour long
programme. I often get home after 6.00 pm, but I can always watch the
6.00 o'clock news.
A PVR is a different paradigm to livetv. Thats the way the devs see it
and thats often the response to complaints/problems with livetv. I'd
like to see MythTV be good at both, but the reality is that the
development effort goes into making a good PVR rather than a good Set
Top Box.
Even still your machine should handle LiveTV for hours on end, but it
may be that there is a bug in a driver that doesn't show up until its
been running a few hours. I know you are using a newer card which may
have driver bugs. This is only a guess on my part.
Also you won't lose your buffer if you exit MythTV and go back in.
LiveTV is stored in a different recording group and normally deleted
after (I think) 24 or 48 hours. It won't show up in Recorded Programs
unless you set it to show stuff in the LiveTV group. Precise button
pushes to do that are not on the tip of my tongue and I don't have
MythTV here to test it.
