If you have some Windows Media Center WTV files you need editing then Expression Encoder 3 (EE3) appears to be the most robust way to achieve this task. I have a backlog of files waiting to be edited but all the available software for WTV editing up to this point was lame. EE3 which has only just recently launched is the first video editing software from Microsoft that natively supports WTV. EE3 also batches jobs and can convert files for all popular streaming formats even MP4 and H.264. Check it out. Nice.
