This is a problem at my work.

We are converting mpgs to wmvs to conserve disk space. Some mpgs convert to wmv perfectly fine. However, there are some mpgs that, once converted to wmv, won't scroll (fast forward) properly, even though the original mpg scrolled fine.

I'm sure the conversion utility is working fine (as evidenced by the perfectly converted mpgs>wmvs)

Here's the thing. There are several different consultants who are taking video (VHS NTSC) and converting these to mpg. Could the problem lie in the source mpg? Is there a certain codec/setting that needs to be used/made when converting from VHS to mpg to allow the wmv (after conversion from mpg) to scroll?

Thanks for any assistance!
