[vdr] vdr hang? while/after dvd-replay

[<apieper@gmx.net>]

Hi,

after a long time i tried to watch dvd and 
experienced the following behaviour:

replay dvd
rewind              -> picture hangs (i guess at chapter-change)
'back' button       -> no effect 
menu, 'stop replay' -> normal tv-picture is shown

after that no more vdr-reaction, tv-picture is still shown.

Because it was in he night i just put off the tv.

When i put on my tv today i had no menu etc. (vdr is hanging)

/varlog/userlog show this:

ps -A show this:
[]
18219 ?        00:01:34 vdr
18291 ?        00:00:00 vdr <defunct>

After 'killall -9 vdr' runvdr reloaded driver etc. and now vdr is running normal.

conf: vdr 1.0.3 + aio26.05

any hints?
