Anyway, the most important thing is that zigzag is disabled.
I had problems with the zigzaging too when trying to troubleshoot my card. It also seemed to not want to stop when retuning, it seemed to continue zigzaging on the new channel, but I am not sure about that. Zigzaging might be good in some cases, but not when playing with the tuner. :-)
The tuning takes 1-2 seconds in worst case. I guess it is the slow afc, maybe it takes time to settle. Are there any parameters to make that a bit faster? Charge pump currents or such?
1-2 seconds is pretty good, don't forget that both the frontend and the mpeg decoder needs to get in sync. I could improve settling time and time-to-picture to under 1 sec by uping the charge pump current and increasing the stepsize, but it can also get instable. I am not sure it would be a good idea to optimize it for your card and just hope it works for all cards on all bands and put it in the CVS driver. I'd prefer having the driver in the CVS do as the manufacturer says, or maybe being trimmed by an expert (which I am not). But hey, give it a try and see what you find! Try different combinations of stepsize and pump current on different bands, and you could also try coarse tuning it with some settings and fine tune it/decrease noise with some other some time later. /ragge -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe linux-dvb" as subject.
