Hi, I'm experimenting using my laptop (a Compaq Evo N1015v) with my Sanyo Z2 projector for DVD playback. I have two specific problems. Firstly I have amanged to create a custom 1280 x 720 resolution using powerstrip trial version, but I can't change the refresh rate from 60Hz. I'm sure the projector can support higher refresh rates, and I have noticed some juddering on pans. It doesn't make any difference whether the laptops LCD screen is switched on (the graphics chipset is ATI Mobility U1 so it has similar capabilities to standalone graphics cards by ATI). Secondly and the most annoying. I bought a Creative Soundblaster MP3+ USB sound card to get an optical digital out to feed Dolby Digital out to my amp. When I use it to feed Dolby Digital I get audio dropouts every 10-20 seconds. They are only momentary but very irritating. I have updated to the latest drivers for the Sound card and I don't get any problems simply playing MP3s or if I set the DVD software to output Dolby Surround via the optical out. Any ideas greatly appreciated.
