Am I asking too much of Movie Maker? While having 80% success with MM on Win7 with issues similar to those reported here, I decided to buy a new HP with Win8. On the first try, I get green screen icons or green screen results on half of my imported MTS files in the Movie Maker window. These file play OK on Media Player, but MM can't seem handle them.

PC:       HP Pavilion

System: AMD A8-5550M APU with Radeon Graphics 2.10 Ghz

            8 gig RAM, 64-bit, Windows 8

Must I pay $900 for Adobe Premier?
