Hi-I have recently started using TiVo-to-go with my 20" iMac and have found when I transfer the recordings, they are showing up "squeezed" with black bars on the right and left (like a reversed letterbox). The finished image is 4x3 but with the squeezed picture and black bars.

I have Directv and my TV is a 42' widescreen Sony. All recordings show up fine on my TV, but the transfers and dvd burns are msessed up. Any ideas?
