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.
