Sorry if this is "oversharing" but I want to provide information so that
I can get this resolved.

THE PROBLEM:
Initially, watching live tv is fine. After some interval (maybe 10 or
20 minutes) or after a channel change, the signal will start to skip and
get choppy, then go black for 15 or 20 seconds until it eventually locks up.
When the skipping/choppiness commences, dmesg tosses a whole lot of this:
ivtv0: All encoder MPG stream buffers are full. Dropping data.
ivtv0: Cause: the application is not reading fast enough.
ivtv0: All encoder MPG stream buffers are full. Dropping data.
ivtv0: Cause: the application is not reading fast enough.
ivtv0: All encoder MPG stream buffers are full. Dropping data.
ivtv0: Cause: the application is not reading fast enough.

Any idea what the problem might be? Suggestions for debugging?
Thanks.
