Hi everyone, I frequently have difficulties when fast forwarding while watching a recorded program in MythTV. It's fairly reproducible; it doesn't happen every time I try to fast forward, but when I fast forward through multiple commercial breaks in a half hour show, it will usually freeze during the third one (jumping forward seems to work fine). When this happens, the image of the screen stays frozen, the mythtv controls show on the screen fine (though the fast forward timer doesn't change). I can escape back to the mythtv menu (though it takes unexpectedly long), and all the white text is now the colour of the TV image that was on the screen. Has anyone seen this before. Any suggestions?
I looked for DMA issues (since that seems to be a common issue here), but the only DMA errors in the syslog were on shutdown. (Sorry for the long description of the problem -- I hope it helps) The log below is from /var/log/kern.log and shows all the ivtv messages while I was using MythTV. (The driver is loaded with debug=1) The problem occurred at 21:20.
