Live TV stops working

[tmiranda]

I've had SageTV installed for just about a month now and recently have been losing live TV capability after putting Sage to sleep and waking it up again. Sometimes if I switch the MPEG Codec from "Sage" to "Intervideo", or vice versa, live TV somes back, sometimes it does not. Rebooting solves the problem but this in not really an acceptable solution.

If I put Sage to sleep and wake it within a few minues there are no problems. If I let it sleep for an hour or so I have no live TV, just a black screen with no audio, no video, and no error messages. I can play recorded shows fine.

I have an ATI 9250 with the latest drivers installed. I'm using the latest (non-beta) version of Sage with Cayars.

I did a broad search on "sleep and no live TV" but could not find anything relevant. Any help would be greatly appreciated.
