Another thing to consider is that pids 0x00->0x1f are low traffic, so with only 6 pid filters available it is someway reasonable to let them pass through group/mask and "software filter" with check_pid. If we move to a more robust filtering structure this can be changed. We could use a sort of open_0x00_0x1f_bandwith and a relative close. Computing an optimal group/mask based on requested pids would be too complex. Having a good software filtering is important if we have to allocate filters for 0x00-0x1f too, expecially if, as I'm reading, some chips don't have the extra 0x310 filters. I'm glad to see great interest in this driver. -- Roberto Ragusa r.ragusa at libero.it -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
