Can you try the attached | patch (against latest hg) and let me know if it helps with this? done & things seem to run here well. attached to a Technisat Gigaswitch 11/20G DiSEqC. we'll test with various other DiSEqC/DVB driver combinations within the next few days/weeks. and i did some more testing with your patch applied to the latest hg and CAM stuff. * when i read data from the DVR device, and remove the CAM and replug it quickly (within 2s), i do not get messages like 'budget_av: cam ejected / cam inserted'. and with a small interruption (1-2s) i get data again from the DVR device (tried about 50 times). no problem whatsoever. * when i read data from the DVR device, remove the CAM and wait until i get 'budget_av: cam ejected', then i get no data from the DVR for around 3-5s and then i get data again. however, when i replug the CAM, and get 'cam inserted', i do not get data anymore. in no case. normally, i get: budget-av: cam ejected budget-av: cam inserted dvb_ca adapter 0: DVB CAM detected and initialised successfully rarely i get: budget-av: cam ejected budget-av: cam inserted dvb_ca adapter 0: Invalid PC card inserted :( also rarely (when re-plugging): dvb_ca adapter 0: CAM tried to send a buffer larger than the link buffer size (65535 > 128)! dvb_ca adapter 0: CAM tried to send a buffer larger than the ecount size! dvb_ca adapter 0: DVB CAM link initialisation failed :( pm | | How is your switch controlled (is it DISEQC)? The problem is when the stv0299 | gets reinitialised, it'll drop the LNB voltage and tone signalling. I did add | code to set the simple tone/voltage signalling post-reset, but perhaps it is | not working right. I can't really resend DISEQC again (if thats what its | using) because that could potentially contain anything. here it works fine now. | | > 2nd problem: | > | > i can decrypt only one channel at once (it is definitely not a CAM | > initialization problem). though, i know that the cryptoworks can decrypt at | > least 3 channels at the same time (and the streaming software can also). i | > am doing this with some other servers (but with wintv cards). | | This I can't really help with - if you can talk to the cam at all and decrypt | a channel, the CI interface is working correctly as far as I know. sorry for bothering - this was an internal problem, one of our CAM cards was not registered... arghhhhh. thanks a lot pm _______________________________________________ linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
