Hi Jim,

I do much the same thing for some of my shows, and I have found that if my
script makes a copy of the original recording into the original storage
directory, but with a '.tmp' extension, then the mythtranscode step will
behave as expected.

I do think it's a bug in that it doesn't make that backup copy, but if that
.tmp file is there, it will delete the original after it has been
transcoded, but recopy (or perhaps rename) the .tmp file back to it's
original filename (in my case it's .ts, but previous versions would be
.mpg).

Just add that step to your transcode script near the beginning.

The end result is that the original show is still in your listings and
playable and all, but there is no longer a cutlist associated with it. I
presume running mythcommflag or whatever it's called will re-create one, or
it can be done manually, but all I want is to have the opportunity to try
again should something else go wrong with the transcoding steps. Generally
it works correctly so after it's been transcoded and saved away, I just
manually delete it.

Hope this helps.

George
