I use Streambaby on my TiVo HD nearly as much as I watch regular recorded programs. In particular, since the YouTube feature is too slow on TiVo, I use a Grease Monkey script to download my favorite UK soaps from YouTube. The 640 x 360 pixel mp4 downloads play at the correct aspect ratio on the computer, but are stretched vertically and squared off with black side bars when played on the TiVo via Streambaby. The same files play fine when transferred to the TiVo with pyTiVo. Is there anything I can do to fix this when using Streambaby?
