I've been watching the threads on the Myth side about this issue. Most of the "lockup" issues I was experiencing with HDTV content have gone away in later versions of CVS. It's the fact I've switched PS / TS, and the fact the recorded streams don't play in mplayer either, that led me to post to this list. I switched to TS about a week ago, and I've already lost audio on: Boston Legal (ABC) CSI Miami (CBS) The resulting files are actually MISSING the audio. mplayer won't play them. myth won't play them. There is NO audio that I can see, unless someone tells me how to detect otherwise. > Closing and re-opening the card re-init's the stream, and the audio > > returns, which makes me think this is correctable. > > > I have a nice strong signal.

Is the ratio I"m getting any good?

Then I'm going to dump the data into RRD and graph the signal strength. Then at least I"ll have a way to go back and look at, say, 29 minutes into CSI, and see what happened.
