The file started out as a OTA ATSC HDTV recording with AC3 2.1 sound. It ended up as a recording that can play back on the MVPMC with mpeg stereo. I think the AC3 was wiped out as the MVPMC digital output is only stereo 48KHz. However, I couldn't get the sound and video on the MVPMC to sync up. It appeared to be somewhere between a second and a faction of a second off. After jumping around it looked better, but never right on. I played back the same recording with mythfrontend and the recording and audio were synchronized from the get go and jumping around didn't change that. So, that's confusing. The video is now playable and clearly has an mpeg stereo audio attached. I would have guessed the transcoded audio and video were not in sync with each other if it were not for the perfectly synchronized playback using the mythfrontend. So, what's the difference between this transcoded recording and a recording off my OTA NTSC tuner (which plays back perfectly on my MVPMC box)? ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
