So quite a while after acquiring an HDHR digital tuner, I was pushed into finally deploying it by my cable provider (Comcast), as they deleted the analog channels. (Though according to people in neighboring towns, they're also planning to eliminate clear QAM, so the HDHR may end up having a pretty limited useful life span for cable.)
Now I'm seeing for the first time what its like to playback an HDHR sourced video with mvpmc, and its far worse than merely out of sync audio. The audio stutters, and the video freezes. mvpmc effectively locks up and requires a soft reset. Is this typical, or is there something else going on here? I'm wondering if the bitrate is too high, in addition to the expected audio problem. The video should be ordinary SD, and as I understand it, cable companies tend to scrimp on bitrates to maximize channel capacity, so it should be lower than ATSC SD. The obvious first thing to try will be transcoding the audio. I'll process one video manually and see how it goes. If that fixes it, I'll revisit Roger's transcoding wrapper script. (Though I don't need the flexibility it provides and will likely use something simpler.) Is it possible to configure MythTV to transcode all videos from a particular source? I think I looked into this before and found you could transcode (run a job against) all videos, but there was no mechanism to only process one particular source. I guess the workaround for that would be to create a script that always runs, and have the script run some SQL to determine the tuner that was used to make the recording. -Tom ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
