SageTV + MyTheatre + 1hr = Micro freezes?

[herrdude]

First of all, let me say that sagetv is fantastic. It is a great piece of software.

I use it mainly with MyTheatre. For some reason, when SageTV gets close to 1 hour of playing live video, I get microfreezes. It seems to be about 10seconds of regular video, 2-3 second freeze, 10 seconds of regular video, etc. The sound is not affected at all. This is with Nvidia codec. If I use the cyberlink codec instead of a 2-3 second freeze, I get 2-3 seconds of excessive pixelation and then regular video. This does not happen at all when I watch with the PVR150. This doesn't happen when I watch recorded shows either. It seems exclusive to live shows with MyTheatre. Also, if I go to MyTheatre when the microfreezes start, MyTheatre continues to show video flawlessly.

If I was to hazard a guess, I would say the problem lies with SageTV dealing with a live large file from MyTheatre (maybe in excess of 1 gig???).

I have found a workaround (but it ain't wife friendly!). When the microfreezes starts, I hit stop twice and then choose the show from guide again. However that basically erases everything before so I cannot rewind before that point.

Any suggestions would be greatly appreciated and tested!
