Update has caused burning DVD problems

[the posse]

I have recently updated to 10.3.6 and i've had nothing but problems since.
Firstly i can't seem to burn my DVDs that i backed up before the update....Example..
I have the wizard of oz backed up and it plays perfect in the DVD player and copies fine using toast 6 with no glitches or MEDIUM ERROR signs popping up but when I go to play it either in my mac or on my DVD player it just won't.
My Mac just spits it back out..
Can anyone help me and not say (change your media) because thats not the problem.
Thanks for any advice Scottie.
P:S I have also reset my disc permissions and still have the same problem.

and it copies fine using Toast 6

elaborate...did you :
Remaster the ripped output from MTR using
DVD2OneX, and then
Copy it by using UDF volume
selection in Toast 6, dragging
your video_ts and audio_ts folders
into the window and burn

or

Ripped with MTR ( or something else)
and then drag/dropped folders and
burned with Toast?

Dl the combo update off Apple's site and run that. After the restart repair permissions.

If that doesn't work create a new user and try to do the above stuff with it. If that still doesn't help then you might have to do an Archive & Install.

I'll try that thanks...
