I don't think so.
How's that for a definitive answer?
I really don't know as I haven't tried this kind of thing before. On the one hand, you are adding cables and connectors to the signal path. On the other hand, with digital video, it shouldn't make any difference. On the first hand, the VP50Pro has a big switching power supply to run it, and possibly more internal switchers inside.
The only way to know is to try it out. And there are two ways to try it. One is to let the DX-5 do the scaling and have the VP-50 just do a "pass-through" on the signal. The other way is to set the DX-5 to output the native rate from the disc and let the VP-50 do all of the scaling.
The big advantage of the VP-50 is that it can do all of the oddball resolutions that were popular when plasmas first came out. Nowadays everything does 1920 x 1080, but remember those plasmas that were 1365 x 768 and stuff like that? The VP-50 can scale directly to the native rate of any display. It uses a big FPGA to do the processing, while the DX-5 uses the DVDO (Anchor Bay Technology) chip that is a dedicated processor. The algorithms are the same, but it isn't as flexible as the FPGA used in the VP-50.
So if your projector has a non-standard resolution, it will probably look better with the VP-50 where it just gets scaled once, bypassing the internal scaler on the projector. If your projector has a standard resolution, it will probably look better straight in, although how much better I can't really say.
We are looking at making a video switcher/scaler for situations like yours. I don't know yet if we will do it, so I don't want to say more now -- just that it may be another possibility.
