What the heck is with this choppy DVD playback?

[NJRonbo]

I thought my T60 was perfect in every way. In fact,
after a few beginners problems and an exchange for
a replacement model, I thought I was just beginning to
sit back and enjoy my T60.

Well, I am on vacation now and [censored]!

Brought my T60 on an airplane to watch DVDs. It
was the first time I got the opportunity to use the
DVD player.

I was horrified to see choppy playback full of slight
freezups every few seconds.

Now, I remember possibly seeing another thread
on this forum addressing the same problem.

Is there a DVD playback problem with the T60
and is there a solution?!

Thanks

MOD EDIT: Yes, this was previously discussed and solved here. Locking this thread to avoid confusion.
