Yes - sould be a bug in VDRADMIN - i made this timer by using the WEB-Interface :-)

What i donīt understand is, that i donīt have changed anything on this system....
Donīt know why this happen.....

I made a diskPerformance-Test now on all 6 Harddrives and watched the messages logfile
for Error-Messages - but - no error-messages in logfile...

The Disk-performance is ok - all diskīs have same performance...


   I think i will delete the Driver and the VDR wich are installed and will install
   a fresh virgin DVB-Driver and VDR and test it again some days....

With this hardwareconfiguration i was able to record 3 Streams and watch a Recorded Movie 
while my Girlfirend watched another Recorded Movie over the Network without any problems
so i donīt understand why this happen now at recording only 1 Stream....

Thanke you and all for Helping !!!!!
