[mythtv-users] Transcoding has quit working 27.4

We are using the bash script mythtranscode_in_fifodir_mode to trans code
to H264 format. It drops all frames because of a constant shift between
the audio and video. Seems to be HD programs and not the ones translated
to HD by the cable or TV programming. This had been working up till the
27.4 update. We did try using mythffmpeg instead of ffmpeg but that made
no change. Most of the time the transcode keeps running and we have to
kill the process as it hangs the job queue. Script and tran coding log
are below.
Script:
