My inability to read the EOP FIQ assembly code correctly lead me to believe that you found a way to tap into the incoming TS and don't steal packets from the ES ringbuffer anymore... > Maybe there is a better way to do this.

I neither have the time nor the reverse engineering skills for it. Thanks for the info, Johannes -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
