Upping the bitrate gives diminishing returns after a certain point, see:


There are other parameters besides bitrate, in addition to resolution there
are a slew of parameters that can be set on the PVR's encoder, but remember
that the PVR is a consumer-quality inexpensive device.

But having said that, a PVR can yield very good results. If I look carefully
I can see the artifacts produced by the card, but most viewers, not knowing
what to look for, do not see a difference between the direct source and a
Myth-reproduced picture.

Beww, so are you saying that this might be normal for myth recordings? Is
everyone using mythtv stuck with this kind of playback problem? It's not the
artifacts that are the problem, it's the lack of smooth playback that is the
problem. I just don't see how any sports fan could put up with this. I go to
other people's houses and watch sports there and I think to myself...I'd
better not invite them over to my place to watch sports, cause that will
make my mythtv setup look really bad.
