Reliability over 3G isn't an issue for me; with just a 1GB data package and a typical TV episode involving ~100MB of download, I think I'll be limited to downloading on my cable connection at home.

I've updated the script to 2.83 from GitHub but not having any luck with the live streams, still not sure if I've got all the possible dependencies in place, but this is not a priority for bandwidth/reliability reasons as above.

The real use that I see for it - which is where PVR comes in - is to specify the TV shows that I want available on the phone, download them automatically overnight by default (subject to being on my "home" wireless SSID), remove anything older than about 1 week to limit disk usage. I can probably achieve that without a GUI, but it'd be nice if there were a PVR application with this as its first backend, perhaps with the potential to add other sources later.
