I am very seriously considering a PVR but I am having trouble deciding which way to go. I have Dish Network so I have narrowed my choices to: 1.)Dish Networks PVR508 or PVR721. I was all set to go this route but then I keep reading nothing but negative reviews. That they are buggy, they don't always record correctly, the set-ups and recording features are no where near as nice or easy to use as Tivo or ReplayTV. The big advantage with this one is no monthly fees and I would be getting the live transmission recorded for better quality and full use of the drive space. Does anyone have any good things to say about these? 2.) A stand alone Tivo to connect to the Dish Reciever. Currently I am leaning toward this option what is holding me back is that it will not be a live recording and I will have to use the 4 different quality settings for recording and I am afraid that I will end up having to use the best mode all the time and not get that many hours from the unit. This one seems to have the best recording features from what I have read. Anyone know how bad the quality from satellite would be on this for the different recording modes? 3.) A stand alone ReplayTV to connect to the Dish Receiver. This one has the same concerns about recording quality as the Tivo. The advantage on this one is I can get Dolby Digital out and Component Video out but I have read the recording features are not as nice as the Tivo. Is the quality of the different recordings any better here than the Tivo. So which of the 3 options do you feel would be the best or which would you choose and why. Switching to Directv is not an option. I signed my father up for Directv a few years back and because it is in my name they will not let me have any sign up discounts for a new address so that is why I went with Dish. Directv would be too expensive paying full retail for all the equipment and instalation.
