Welcome to AVS Forum!
I too have an RPTV but I have a DLP. It sounds like your RPTV is CRT-based. I suggest you read the October (I think) Widescreen Review of the Bravo D1. This will tell you a lot about the DVD player but more importantly, it dicusses the relative merits of an upscaling, DVI-output DVD player for different display technologies. The idea of a DVI-input to your TV is to reduce (in the case of CRT displays) or eliminate (in the case of fixed pixel displays) digital-to-analog and analog-to-digital conversions. There is a lot of noise introduced to the signal path by these conversions, so reducing them is a good thing. By the way, the Bravo D2 will be out in February (reportedly) so you should wait for that.
If you don't have a DVI input, DO NOT BUY a Bravo. Period. There are other DVI-output DVD players coming out this year which probably have better component circuits (just in case you were thinking of getting a DVI-output DVD player for the future
). I'm not sure why V Inc. included component outputs, but they sure didn't waste any money on the quality of them. As for these upcoming players, you will need to find out if the one you are interested in does upscaling through the component connection - some do not!
