Converting wmv to mpg?

Can anyone recommend a good freeware video converter? Specifically, I want to convert .wmv to .mpg. Thanks.

You can try TMpgEnc. It only encodes to MPeg-2 for 30 days (due to licensing issues), but MPeg-1 encoding remains available.

I just tested it on (presumably) a WMV9 source. The extension .wmv isn’t recognized in the “open file” dialog, but if you set the filter to “All files (.)”, it works fine.
