Just seems a bit odd.

Yeah, thats a good idea. > Alternatively, try just checking bit 6 and ignoring all the other bits in > your wait_if_status. Thats exactly what it does do. The extra printout was just for debugging; the problem is it never sets DA after I set SR. In fact, it looks as if setting bits on the control interface has no effect on the status register. -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
