[mythtv] Newbie questions about mpeg2->mpeg2 transcode.

[Britt Houser]

Ok, thanks for the clarification.  I thought that hitting X in the
frontend was like typing 'mythtranscode' from the command line, but I
see they are two different things.

My ultimate goal here is to take stuff I've recorded, edit out the
commercials, and 'export' them out of myth and store them on a
seperate file server.  Then I NFS mount this directory on the
fileserver under /myth/videos and I can watch them that way.

So after I mark these commercials, I hit X, and the transocoding will
start, and the resulting file will be mpeg2?

Thanks again for the help, like I said, I'm a newbie as transcoding stuff.

thx,
britt
