I think your best bet would be to go back to kmttg and with the help of folks on this forum, figure out what is wrong with your files or your ablilty to play them. Forget tivodecode. Use kmttg to download and decrypt a file from your TiVo. Make sure you are not set up to download TS format but the older PS format. Start fresh with a program on your TiVo, not a .TiVo file you already have. kmttg will download and convert to .mpg all in one operation. Run mediainfo on your resulting .mpg file and post the results. We can then see what is going on with your files.
