I have two series 2 TiVos, an older single tuner (ST) model and a dual tuner (DT). All shows transferred from the ST model play correctly on my PC. All shows transferred from the DT are "squished" -- that is, they are too tall. Both the "TV Aspect Ratio" and "Video Smoothing" options under "Messages & Settings->Setting->Video" are set the same on the ST and DT (4:3, smoothing off). I've tried transferring the shows with both pyTivo and TiVo Desktop. I've tried recording the same show from the same channel for comparison. I've tried using the TDCM tool to check codec preferences, but couldn't find any option such that video from the DT played correctly. I'm using Windows Media Player 11 on Windows Vista. Any suggestions?
