Got a small problem and can't figure it out. I have my pc hooked up to a hdtv and everything plays back fine, except wmv files. I have a dual video card with a monitor on one and a hdtv on the other, connected with a DVI. The wmv files play back fine on the monitor, but when I play them back on the hdtv all I get is sound and a black screen. If you need to know computer spec, I will have to post them later. I thought it might just be something to do with the format, since everything else works. Thanks for your input.
