From Bob's response on another thread:
Check your DVD player specifications. I have three dvd players that will play WMV movies from a CD or DVD burned as a data disc (Toshiba, Philips, and Sony).
I don't have a TV hooked up to my workstation so to check lighting, spacing, etc. as it will appear on a TV I go thru the DVD creating process and check it on 2 or 3 TVs. If one of my DVD players will play a WMV file, will the display be close enough to DVD to evaluate the settings? Getting the brightness/contrast settings acceptable always takes several iterations and using a WMV file would certainly speed things up.
