[clug] transcoding MythTV files to divx or DVD size

[Paul]

I have a 7Gb HD file which I need to shrink down to at-least 4G or even 600Mb, so I need 
to compress file, and I don't have any Cutlists (AFAIK)...

Any particular output option more reliable... note my export works for a few other files I 
tested which weren't HD so perhaps something in the stream which is causing encoder to fail.
Garrg I might if have to try windows utilities...
