I've been having trouble transferring recordings from TiVo to PC and wanted to document my experience for others.
Here's my set-up:
TiVo series 2
Vista Business Sp1
Problem: Unable to transfer recordings more than about 1GB. I get the "Transfer Interrupted" error.
When I was on TivoDesktop 2.6.x was able to transfer files greater than 1GB, but that stopped working at some point with 2.7.x. I tried the following to fix the issue, but ultimately uninstalled 2.7.x and reinstalled 2.6.x
1. altered my Windows firewall settings;
2. turned off virus protection completely (Avast).
3. restarted TiVo box via the menus.
4. transferred files via the browser interface (no problem with files > 1GB)
5. installed and now use pyTivo to move and watch movies from PC to Tivo (nice!);
6. downloaded Galleon, but did not install (used to move files from Tivo to PC); I just stuck with TiVoDesktop 2.6.x since it works.
