I don't use the inbuilt transcode functions, so don't recall off the top of my head what parameters, if any, they need.

But the first thing that occurs to me is that I believe that rebuilding the seek table will invalidate commflag markers and cutlist markers, so if you were transcoding to remove commercials and pre / post padding you may need to rerun your commflag detection and rebuild your cutlist after rebuilding the seek table and before transcoding.

I think the parameters passed to the inbuilt transcode can be seen from mythtv-setup on one of the screens near where you setup the user jobs. Under General somewhere I think.
