It seems this isn't something that's on the tip of everyone's tongue, so
I did a quick experiment. The database knows that the current file is a
.nuv file. I probably don't want it, but I renamed it in case I change
my mind. Then I made a backup of the original recording (by now called
.mpg.old) and renamed it as .nuv
This played within mythtv, but I couldn't edit it: said there was no
index. So I tried a lossless transcode. After that I was able to edit
it and create a cutlist. Another lossless transcode and I have an
edited file that plays in mythtv and contains mpeg2video and mp2
streams. The starting bookmark was perhaps rather persistent - maybe
this is normal. The file is still labelled as .nuv
