You have to _boot_ your system :) It doesn't "Just Run" ?!

I would first try slowing down the record rate. I have half a bazillion
DVD's here that _claim_ to be burnable at speed x18 or x32 or xbazillion
but they really only work well at x2 or x4. All of the dual layer disks
I have to burn very slowly or else I get a new coaster.

I miss the AOL CDs. They made such good coasters.

I digress....

Dropping and freezing on playback is a decompression problem with your
CPU/IO having a problem. Either the bandwidth is too slow or the CPU is
bogging down and the result is a freeze or dropped section to keep up.

That said, I have had no problem playing DVD's (commercial pressed
movies) on IBM Thinkpads running 700 MHz P3's with 512 MB RAM (Fedora 4
with Ogle as the player) even in full screen mode. So I suspect there is
a failure elsewhere.

Test the player with commercial disk. Then make a test copy of the disk
and try the player with the copy. If the copy plays poorly, make another
copy and slow down the burn speed to x1 or x2. If it still is crappy,
you may be looking at artifacts from copy-protection stuff.
