I thought I would toss out to everyone that today, while NCIS was recording on my pcHDTV-3000
(and I could watch the file enjoying all the skips and broken video/audio) I could tune
to it on my pcHDTV-5500 and watch it live with no problems.
I've already adjusted (in the past) the preference from recording on the 5500 to the 3000 to see
if that would help and it doesn't seem to make a difference.
The cards are both set for a tuning delay of 0 and a 2 demux'd channels per card.
p.s. I record Life Unexpected in HD and it's usually fine (different channel).
Makes me wonder if there's a comcast issue.

Once, there was NO fun ... This was before MENU planning, FASHION
statements or NAUTILUS equipment ... Then, in 1985 ... FUN was
completely encoded in this tiny MICROCHIP ... It contain 14,768 vaguely
amusing SIT-COM pilots!! We had to wait FOUR BILLION years but we
finally got JERRY LEWIS, MTV and a large selection of creme-filled
