MOV to WMV....ugh

Flip4Mac: awful translation of gradients and lights, no custom settings for the Standard edition. Pro (where you can increase the bitrate) is a hefty $160

Aimersoft Video Converter: free edition comes with a watermark. Used a high bitrate but still looks awful.

Wondershare: watermarked, but good quality.

MPG streamclip: uses Flip 4 Mac, awful at default, $160 to upgrade.

MacX Video Converter Free Edition: keeps crashing

MPG converter: won't do larger dimensions

Tune4MAc: fails

WinXMOV converter: crashes

http://video.online-convert.com/convert-to-wmv just as bad as Flip4Mac

PCHand MediaConverterPro: unregistered version converts up to 3 minutes

In conclusion, when you're on a Mac and you have to convert MOV to WMV your best bet is Flip 4 Mac. (Or to kick it old-school and find a Mac with Cleaner installed that always did a nice job for us in ye olde times...)
