Ok - that's what I expected, unfortunately. :( Moreover I forgot to mention that if I start a DVB-Scan after certain walkthroughs the filter timeout pid problem appears right after trying the first transponder (= initial transponder), which is equal to a card driver oops. Consequence: The machine must be shutdown (i. e. NO soft reset helps!), then be restarted, and then "scan" got to be run again. That appears like a "plug and pray issue", highly Microsoft-compatible! My card is a Pinnacle PCTVSAT PCI, i. e. a bt8xx-based DVB-S card, whose drivers are maintained (well, whatever that means in this very special example) by Manu Abraham. I did a little research in the dvb-apps repository, and noticed that very long time ago Johannes Stezenbach pulled in a patch to lower down the maximum number of running pids from 32 to 27. Whatever card he used as a reference or even proof that this would help to resolve the filter timeout pid issue remains a secret for me until today. So the perspective is to wait until Mister Abraham has finished his cx878 project (or should I call that a dead born child either?). As four unusable kernels (at least for bt8xx-based DVB cards - 2.6.13 - 16) showed in the past the ultimate Abraham-based top record of waitstates amounts to 9 months. I wonder if he can top that this time! So I am forced to build up a deeply horrible list scan feature as part of my TCL-TK-project, because if I do the channel scan transponder by transponder (i. e. list-oriented), using parameter -c plus a loop I get reliable scan results. That's highly time consuming, but that at least works. This option I wanted to avoid - this is what we call bad fate! > > P.S. > I've just added check for CA descriptors in PMT to correct CA flag in some > cases. In kaffeine I suppose - looking forward to kaffeine's next release. :( Many thanks for your hints!
