Running a PVR-250, currently at 720x480. I notice that in windows MP there is no way to force a 4:3 image with a 720x480 image, so it makes it a pain when moving recordings to the theater room. Since TV is approx 640x480 with extra info (the 720 width I assume), is there really any "loss" to recording in 640x480 instead of 720x480? Thanks, Ben
