Thanks Jaakko, I have not had much time to test the card, but indeed the signal seems to be at its limits, certainly not saturated. Simply holding the card's internal coax cable gently between thumb and index finger improves reception. If the internal video cable is at wrong position there is no reception at all. When I originally suspected there might be saturation, Robert Schlabbach suggested to check HALFADC and SATADC registers. I added some printks to ves1820.c's ioctl part. There was no saturation on the registers 0x21..0x27 except with register SATDEC3. With qam64 steram the values or SATDEC3 are around 0..4 and with qam128 the values are around 0..15. Halfadc values flucatuate in the range 0x50 .. 0x90. Other registers stay at 0. I tied to change Ves1820 registers AGCREF and AREF via the proc interface Dennis has written. I have tried different values but so far no help. I have also one DVB-C budget card and will try later if that has any better reception. But I guess I have to start harassing house manager and the cable company, HTV. Jarkko -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
