[mythtv-users] mythtranscode and nuvexport (memory usage and swapping)

If you're hitting swap, then one of the nuvexport calls is broken and 
the fifo is getting disconnected (audio or video), which causes 
mythtranscode to continue to write to the fifo (which is cached in RAM).

Which program?  commercial_cut or avidemux?  afaik, avidemux is the ONLY 
program capable of cutting mpeg files at places other than the GOP 
(necessary for cutting commercials, which may or may not fall on a GOP 
edge) without reencoding everything.

Once and for all, please learn that THERE ARE NO HD nupplevideo files 
from myth, unless you use mythtranscode to convert them to mpeg4.  If 
you record HD, what you see called .nuv is really an mpeg2 TS (or PS, 
depending on settings) file.  Only thing that makes it not look like an 
mpeg is the fact that the filename says .nuv instead of .mpg.  Same goes 
for files recorded from pvr-x50 cards.  They're *not* nupplevideo, but 
standard mpeg recordings in standard mpeg containers.

Currently, and I don't know why, nuvexport does NOT work with TS files. 
  I haven't had time to debug it (only recently got an air2pc card), and 
don't really know enough about ffmpeg/transcode/mencoder to figure out 
how to make them work.  (I'm open to help if anyone knows how)
