I have a Tivo (I think series 2) HD DVR that has started "skipping." That's the best way I know how to describe it - skips just like a scratched CD. Sound and picture freezes for a second, then resumes. Sometimes it happens with such frequency, it's unwatchable. Seems to happen more often on the HD programming, and on recorded programs, then with live standard def shows, but I've seen some skipping on those two, so I can't seem to find a real pattern. But I am fairly certain it's the Tivo unit and not the satellite or anything else. Is there anything I can try to fix this on my own? Is there anywhere (in the NYC area) that I can go to get it fixed? I bought this used off of eBay so there's no warranty or proof of purchase or anything like that. I think my only hope is to fix this box. I can't buy a new Tivo because I have DirecTV and from what I understand, the new $299 series 3 box won't work. I can't buy a DirecTV DVR either because I plan to switch to Verizon Fios in a few months. Plus I really really want to stick with Tivo. I think if this box is dead, I have no options for HD DVR at all, so I'm really kind of in a bind here. Any help is appreciated. Thanks.
