There's at least one transponder here which appears to work perfectly. femon reports a slightly higher ber, if anything. No transport errors reported by xine. No uncorrected errors from femon. > >I'm having problems with the sp887x card too.

What about the tda1004x - do you trust its counters? I'm definitely getting packets flagged as errored from the demux device while the uncorrected error count is always zero. I improved my antenna setup slightly by putting in a preamp before a longish cable run from the wall to the pc (over low quality cable too). I received the problem transponder for 7 hours without error until xine stopped working for some other reason. So I suppose it is just a signal quality problem, despite the fairly low ber (< 0x150) and no reported uncorrected errors. thanks, Hamish -- Hamish Moffatt VK3SB <[EMAIL PROTECTED]> <[EMAIL PROTECTED]> -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
