I just moved and I am waiting for Comcast to install my HDTV service. I have a home theater that requires the optical dolby digital connection. I called TiVo to purchase the HiDef dvr but they warned me about the recorded play back quality - has anyone experienced this? How bad is it? Also I want to take advantage of the muli-room viewing so I would need to puchase an 80 hour standard definition dvr. However I do have an old svr-2000 who's modem has been replaced with the ethernet card. I can not transfer my service so I will keep this box running. Anyone have any opinions or any heads up for me? Thank you!
