Query: the best ever (slightly better than TiVo)

I own I original ReplayTV, 2 RTV5504 and 1 TiVo. In my opinion, the TRV5504 is the rules. It has a Ethernet connector built-in so you don't need adapters like you do with a TiVo. I also like the user interface much better. It might not be as fancy as the one of the TiVo, but in this case less is more. Another advantage is that the unit offers the 30 second skip (great for commercials) right out of the box. On a TiVo you have to use special codes to activate that feature. Other great features include the component output, streaming shows between multiple units and programming over Internet. After the first day, I said that this is the one gadget I will never give up again. The only minor disadvantage is that conflicts between scheduled recordings can occur due to a bad priority list. Overall it is still much better than any other PVR/DVR I have ever seen.
