I've changed this and since 2 days this problem is gone. And I've observed, that the UPT-error occurs not as frequently as before that changes. For example: Now I can do a channel switching over 80 channels before the error occurs. Before that, the error occured even after 15 switches. Maybe we should debug the UPT-error in that direction... vdr 1.3.1 (without patches), DVB from 4.1.2004 (with pids_off=1) Martin -- +++ GMX - die erste Adresse f�r Mail, Message, More +++ Neu: Preissenkung f�r MMS und FreeMMS! http://www.gmx.net -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
