Advertisements I'm looking to buy a TIVO, most interested in a DVD-R, dual tuner. The more I look into the different models, the more questions I have. Which TIVO is the fairest of them all? Here are my questions: 1) Is it worth it to buy a DVD-R model? Is the video/audio quality on DVD-Rs as good as the non-DVD-R models? 2)What is the best, most reliable TIVO DVD-R? From the customer reviews I've read, it seems the Pioneer 810 is the one customers like best. What about the Pioneer Elite? 3) I'm looking for a series 2, dual-tuner model. I don't have an HD tv, so don't need a series 3. I've read that some say the TIVO 240s have better video/audio quality than the newer models, but then also read that the 540s and 640s have better technology. Which is the best TIVO model and why? 4) Do I need a USB2 adapter if I already have a wireless network set up? 5) Because they don't make the TVIO DVD-R models anymore (grumble, grumble ), I'm looking at used ones on Ebay. If a drive has already been upgraded (I'm only looking at reliable sellers), should I stay away? I'd love to have an upgraded drive, because, well, I love my TV, but not sure that I'd want to attempt upgrading myself. I know my way around tech stuff, but never upgraded anything before. How techie should I be before attempting an upgrade myself? Also, if I buy an upgraded model, should I insist on having the original drive? Is having a warranty on the upgraded drive enough? This part is where I get the most confused. Thanks!
