Re: low resources

Björn,

Switching to the 800x600, 15-bit color, or 640x480, 16-bit color, 
enabled me to run Ogle without the Xv extension. Thanks so much for the 
help!

I have three other questions:

1) What is the yuv2rgb conversion?

2) Are there other ways you might suggest to maximize the resources of 
my older 266 mhz machine? For example, would a windowmanager like 
Blackbox or WindowMaker consume fewer XServer resources than the Gnome 
desktop? Any other hints for fine-tuning Ogle for the machine?

3) Would a PII 400 mhz machine perform substantially better on DVDs than 
my current processor?

Again, I sincerely appreciate your help.

Best,
Ted
