You can convert Tivo recordings into a format playable on a Sansa e280 with free software, but it's a lengthy, awkward process:

1. Download the Tivo recordings to your computer using the Tivo Desktop software.
2. Convert the .tivo files to ordinary .mpg files using DirectShow Dump.
3. Convert the .mpg files to .wmv Windows video files using Windows Media Encoder.
4. Open the .wmf files in the Sansa Media Converter program. The file will be converted (again) and then will be copied to your device.

It's unfortunate that step 3 is necessary. But the Sansa Media Converter refuses to open the .mpg files created by DirectShow Dump. It gives an error message of: "This file ... cannot be imported, please install the codec first. If the files can playback on your computer, probably the Sansa Media Convert does not support this format, or the file is corrupted." In fact, the files do play on my computer.

This is a time-consuming process. For a one-hour program, step 1 takes about an hour, step 2 takes a minute or so, step 3 takes about two hours, and step 4 takes a few minutes.
