Xine is my choice for commercial DVDs; VLC for the streaming formats 
(youtube, etc. captures to .swf files).  YMMV.
As for your jerks, you might want to be sure dma is enabled:

        [root at mavis ~]# hdparm /dev/hdc
         /dev/hdc:
         IO_support   =  1 (32-bit)
         unmaskirq    =  1 (on)
         using_dma    =  1 (on)
         keepsettings =  0 (off)
         readonly     =  0 (off)
         readahead    = 256 (on)
         HDIO_GETGEO failed: Inappropriate ioctl for device

If that looks  copasetic, you might want to try another DVD or two 
before changing too many of Xine's several options.

        [root at mavis ~]# wc -l  /home/rj/.xine/config
        838 /home/rj/.xine/config
        [root at mavis ~]#



As far as processing power, I've watched dozens of movies on this 
machine running an AMD Athlon(tm) XP 2600+ at ~2GHz and 2GB ram, which 
worked every bit as well as it did when I had only 512MB.

I have watched a few movies on another box running an P-3 at 1GHz and 768MB.

BTW, you really need to send properly threaded messages with a 
meaningful subject if you want to attract the best help possible on this 
list.  A lot of these guys do this stuff for a living and simply don't 
have time to sort through everything.  Traffic here is 'way less that it 
is on the Fedora list and you might want to try NOT using the digest mode.
