Funny, I don't have a problem with digital- best thing since sliced
bread for me. In fact I have trouble with analogue because I use a tv
server- the adc doesn't work as efficiently, whereas digital is already
mpeg.
My biggest problem is HD where my video card has to resample the image-
it stops and starts a bit because my video card is not HD capable. My
tuner, hardware, and monitor can though... I'll update the card soon-
its an ATi Radeon 9250 with 128mb.
