I'm playing around with some options for hooking up a HTPC to my Pio 433MXE. Currently I can watch TV via the Nebula card, and DVDs using a Tosh drive and TheaterTek. I use the DVI output from a Nvidia card, and PQ is very good. Just wondered if Dscaler would help improve things, but I don't think it works with the Nebula card?? Does it have any influence on DVD playback?
