[MPlayer-users] Eagles - Hell Freezes over DVD

[Ni Bo]

Hi Vladimir, thanks for the quick reply!

I'm only blaming the DVD because the second DVD I tried (Desperado, if it 
matters?) is of excellent quality overall.  I'm not expecting perfection at 
this stage as I haven't explored all the options of mencoder, but Desperado 
I would say is at least a 100% improvement on Hell Freezes Over...

The command line I used is below (called from a script, hence the '$1', '$2' 
etc)
Video issues with Hell Freezes Over are 'blocky' video, particularly scenes 
with dark backgrounds, people with dark clothing etc. Also the 'fog' 
generated on stage appears blocky. (This is one of the reasons I chose 
Desperado as my second attempt - there's a few smoking scenes)

A second problem was that fast-moving scenes tend to appear 'streaky'.

Thanks for your help! Let me know if you need any more info.

-oac copy -o /mdata/media/video/$2.avi

I've also tried the xvid codec, but get a 'jerky' picture...
