Ever since I upgraded to Windows 7 (RTM, x64), I kept having problems with my extender (DMA2100). I could plays all my videos, but after about 10 mins in the video, it'd stop without any kind of warning and just go back to the folder where it was selected. Playing recorded shows (both wtv and dvr-ms) doesn't have this kind of problem; it only happens with "non-recorded" material (I've tried avi encoded with divx and xvid, and mp4s). I am on wireless, but it's not that far away from the router, and VMC never had this problem. Any ideas? Thanks!
