I was watching some NFL (american) football today on an HD channel (approx 3+ hours of continuous timeshifting), but about half way through it the video and sound got into a loop for about 10 seconds, and then hung and went silent. I saw a generic windows error box appear for a second, then get hidden by mediaportal.

Then a few seconds later, the show started playing and timeshifting normally again, without me having to do anything.

Once the game was over, I quit mediaportal, and got the following info from the windows crash message:


AppName: mediaportal.exe AppVer: 0.2.2.9993 AppStamp:4760755b
ModName: tsreader.ax ModVer: 0.0.0.0 ModStamp:475061da
fDebug: 0 Offset: 0000a1e4


Does anyone know what could cause this?

Thanks,
Dan
