I've been using WM7 for my HTPC and I am thinking about getting Arcsoft Totalmedia Theater 5. I need support for m2ts and dvrms and I want something to improve low quality video. I have the HQV video processing chip in my Surround Sound reciever and it does a great job with 720p, 1080i, and other HD sources, but it doesn't do much to standard def.

Is TMT5 worth the money?
What other Software is reccomended?
