Even though it looks like this topic has not raised much interest, I think it is important and really should be addressed. VDR has failed recording periodically scheduled programs many times here because the program transmitted after the recording was encrypted. So the next scheduled recording the following day was not started because the channel was marked encrypted in the channels.conf. And VDR mainly being a video recorder this really is a serious bug.

[vdr] Handling of temporarily encrypted channels
I am using VDR 1.4.5 with the integrated auto pid feature and without any CAM. When tuning to an encrypted channel, the CA value gets set accordingly and channel not available is displayed. So far so good. However there are channels that encrypt only certain programs and are free the rest of the time. When tuning to this free channel while the program is encrypted, the CA value will be set and channel not available shown. But when tuning to the same channel again when it is not encrypted any more it seems that VDR just checks the CA value and displays channel not available instead of checking the currently broadcast CA value. So the channel cannot be watched even if it is free in the moment. This is quite annoying and decreases the WAF a lot :-/ Is there an easy way to fix this? -- Ondrej ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Edit the file dvbdevice.c, insert a line return true; at the beginning of the method cDvbDevice::ProvidesCa. With this modification you can tune to encoded channels, however you'll never see a channel not available, you'll just see a black screen. This, btw, also solves the problem of channels that declare they're scrambled when they aren't. Bye -- Luca A: Because it destroys the flow of the conversation Q: Why is it bad? A: No, it's bad.

With this modification to dvbdevice.c, I wonder if VDR will still crash when a timer goes off on a channel and all the sudden it becomes encrypted. This would normally cause a broken data stream and VDR would do an emergency exit. Regards. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

hi, Stone writes: With this modification to dvbdevice.c, I wonder if VDR will still crash when a timer goes off on a channel and all the sudden it becomes encrypted. This would normally cause a broken data stream and VDR would do an emergency exit. I gave up recording encrypted channels with VDR a long time ago. The problem is the VDSB error or something that results in a rebooting cycle for the VDR. It tries to solve the problem in a wrong way, assuming that all delays in starting the video stream are due to driver crashes. While, of course, it is natural to have delays in starting to view an encrypted channel, but the driver's have not crashed for perhaps 1.5 years now. When live viewing, VDR is much more patient and is able to wait without the emergency exit until the right authorization information is given to the smartcard, and the decryption starts. This can take even half an hour, or 45 min even in my setup (at least it has taken a couple of times that long). (Of course the provider does not change keys every day, so the longer delays are not frequent.) When VDR tries a timed recording it has no patience to wait for the decryption to start, so it might sometimes succeed (if the provider has not just changed the keys), or then it just destroys all other recordings with the restarting cycle. So it is better not to try to record an encrypted channel. yours, Jouni ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
