The system is pretty stable and is powered up all the time. Kernel is linux-2.6.15.6 and IVTV is 0.4.5. The TV is connected to the PVR-350 and the audio goes through the optical out to the AV-receiver.
I don't think the system load is significant as I frequently run a script to compress the mpeg to xvid in a matroska container, during this time the cpu is running at about 100%. Simultaneously, I record something and watch something else without any noticeable problems. The only problems that I have are: After several days to a week or so the audio disappears from the mpeg stream, earlier versions of ivtv this problem occurred more frequently. The ivtv X-Driver occasionally crashes. Duncan _______________________________________________ ivtv-devel mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-devel
