Kevin,
I can certainly see how if it's having slight decoding issues in audio or
video that it could be slowing down and catching up, leading to potential
cumulative delays by the end of the day. I've never seen it happen, but
that's not to say it couldn't.
Especially since every time you change channels the buffer would normally be
wiped, but you're staying on the same channel.
If you want it "sans delay" and outside of MCE, what about the option of
disabling the eshell processes and running the TV Tuner card manufacturers
live tv overlay application?
just thinking out loud..
