So I started watching the disc in question on my Windows laptop and it 
hung during one of the episodes. Restarting WinDVD and playing with 
where I was in the stream got past it; but with that I called it bad 
disc and got a swap'd out set today. So it seems the first issue (likely 
a header issue) was able to be gotten around easily, but with the second 
hang there seemed to be multiple issues.I confirmed all new discs are 
readable by Xine - at least to load the disc. Now I (joyfully) get to 
watch them all again to confirm they are all 100% good discs
.
Any how...would be nice for a little better error correction too; I 
wasn't quite ready to call it a bad disc with just the header issue; but 
with a second issue there was definitely something wrong at the disc level.

Thanks for all the help and tips.
