Hello, MrGrey1!
Quite frankly I wonder why you'd even bother with WMV(Windows Media Video). Even at the best of times, WMV is blurry and indistinct. MPEG2 at DVD SP grade is far better. If you want to go higher grade again, there's MPEG2 at DVD HQ, except what little extra image quality you gain, is at the expense of capacity on a standard 4.7 Gb single-layer(DVD5) disc. At DVD HQ, you can get a shade over one hour but at DVD SP you can fit close to 2 hours 25 minutes on a disc. Other video file types offer greater quality again but require Blu-Ray discs to carry such a degree of quality(AVCHD, for instance). Not many people have Blu-Ray, as yet(some cite the expense of the discs and the hardware to burn them as a reason why they don't have Blu-Ray). Most computers come with DVD-RW drives as the standard for their desktop or laptop models.
Cheers!
Neil.
