[mythtv-users] nuv->avi possibilities?

That's because they're not nuv files.  They've just been named as such.

Probably, yes.  It's a LOT easier to code file interaction when you 
don't have to check "if (file_extist("$file.mpg")) ... else if 
(file_exists("$file.nuv")) ..." and can just assume.

Then again, I personally think it would be nice to avoid user confusion 
and use nuv or mpg as is appropriate for the file.

Those wouldn't be accurate representations.  The software-encoded files 
ARE nuv files, not "rtjpeg" or "mpeg4" files.  The video inside of them 
might be one or the other, but nuv represents the container format 
(which contains meta data, etc).  The mpg stuff is a little more 
confusing since mpg represents video and audio codecs, as well as a 
container format.

Though as I said, I'm all for naming the mpeg-based recordings .mpg 
since it'd clear up a heck of a lot of user confusion on the issue.
