Because it is weekend i was able to test some more variations.

VDR 0.99 don't ran that stable as i thought, i only never 
noticed this because i never used it that intensive.

For the tests with gdb i started DVD, partly pressed 'yellow',
stopped it (back-key), moved a bit in the menu, started DVD
again and so on.

With vdr0.99 dvd seems to work a little bit more
reliable than with 1.0.0.pre4. I was not counting
exactly, but i guess it took 4-5 DVD-starts before
vdr exited, with 1.0.0pre4 vdr exited on the second time
i tried to replay DVD.

First time dvd-replay works always.

In case its important: my dvds are located on hdd.
