Idle system causes corrupt recording on last viewed channel

[arizonamythtv@…]

I'm compiling 0.24 on Mythbuntu 10.04 AMD64 using a PVR150. I'm controlling a STB with a IR blaster. When the system sits idle for a few days when I attempt to watch or record the last viewed channel I end up with a corrupt recording. I know the IR blaster switched to the proper channel as the STB OSD shows the correct channel change. I've checked the db and it comes back with no errors. As a work around I run a cron job to switch the channel to an off channel that I wouldn't record then I start liveTV the recording works properly.
