Odd playback problem

[Shiko]

I have a few backed up dvds, which were done using dvdsanta.

Both were backed up as an iso, then reburned as an iso. However, only 2 of the 4 dvds work.

Two of them when put into my dvd player work fine. The other two tell me its not a supported playback. They were all burned the same way, on the same verbatim media. So I tried reburning them to a dvd again (in case of a bad burn) and still get the same problem.

What can cause 2 dvds, backed up and burned the same way, on the same media, work differently in a dvd player?

In case its needed, the dvds were:
Open Season
Happy Feet
Bourne Identity/Supremecy.

Hi!

What can cause 2 dvds, backed up and burned the same way, on the same media, work differently in a dvd player?

A ripping program that doesn't properly/fully handle differing types of copy protection.

I'm guessing that your 2 problematic DVDs are "Open Season" and "Happy Feet"...
