[mythtv-users] why are the mythtv stream files different fromstandard codecs?

[Rob Snow]

Here is what I use for one of my scripts, this one is designed to put 3hr's 
of DIVX on one CD.  You might want to adjust the audio/video ratio's if you 
are doing something with nice audio.

I have 2hr/3hr/4hr/6hr scripts that I use to convert my 2Kbps MPEG4 .nuv 
default captures to something that I can actually carry around on the 
laptop, burn to CD for my wife or family since .nuv is useless to them.

I use a cron job with a find /e/store -mtime +2 to get anything I haven't 
already deleted in 2 days and convert it and rename it using the other 
script I previously posted to name it by extracting the Title:subtitle from 
the database. 
(ie. 1059_213412431432_243132412314.nuv --> SG-1:Emancapation.avi)

I just need to write another script to delete the .nuv and database entries 
from Myth once it's done.

I should probably up the 2Kbps MPEG4 to around 4Kbps (~2GB/hr) since they 
are going to be converted pretty quickly to something else.
