Just had Motorola 6208 DVR installed last Friday. Love the DVR part. New cable box is kind of noisy but I can live with that. What I do find problematic is video signal quality on lower channels, like Fox or WB for instance. It looks a lot grainier than with the old non-DVR cable box. I've even double checked that on my 2nd TV that's still on the old cable box. I have it hooked up to Sony 61HS10 via component cables. BTW, HDTV channels look great. Does anyone know if that's a known problem with a box or/and Comcast? Any ideas on how to improve the picture quality? Please share your experience if you have a similar setup. Thanks in advance.
