I've settled on XVID/AAC codecs in an MP4 format(ushare is able to share mp4 video with the 360 via upnp). HD recordings are resized to HRHD(960x540) to be compatible with the original XBOX with minimal loss of quality. After months of testing and digging, I *might* have found the holy grail script. <br><br>After recording(PVR150, HDHomeRun), a user job is kicked off to transcode the file and reinserts into mythtv. Thus far,
I haven't seen any audio sync issues, but it's too early to claim 100% success. If anyone wants the scripts, I can post them.<br><br>My question is: when viewing the recordings through mythweb, mythweb is unable to create a screengrab of the MP4 transcodes. I get the following in the
