Huh? More ram does not make your computer faster!!

Actually, in your case, it may make it slower... Most Super7
motherboards (used with K6) have an idiotic design flaw where they
cannot cache memory above 128 megs, so your system would probably get
a lot faster if you dropped down at only 128 megs of ram instead of

Also, keep in mind that your system is *very* borderline for playing
DVDs to begin with. Most mpeg4 files you'll find are 512x256, 512x384,
640x288, 640x304, or at worst 640x480; on the other hand, DVDs are
720x480, and that's a lot more pixels!

You can try dropping to 128 megs, using -framedrop, or perhaps
clocking up to 550 if it's stable... My K6-3+ can play DVDs now at 500
MHz, but just barely, and it has a much better on-chip cache than the
