So there is may be a check for the provider name. Not exactly. As long as there is no necessity to reread the PAT (Program association table) everything is working fine. At the current state the mechanism (or system call) to restart or reset the reading and parsing process of PAT, SDT, PMT is missing. And that exactly poses the problems as soon as you change the transponder.. As long as you do not change the transponder, PAT, SDT and PMT stay the same. Transponder is not equal to provider google is your friend or have a look at etsi.org... Yes, but I have tested a Transponder change, where the Provider name of the new transponder is the same as before, then alevt changes to a new channel (may be the first one) and continues to work again. As I have edited my kaffeine channels.dvb on my own, I am very sure, that I have changed the transponder... Is your version 1.7.0 connected to the version 1.7.0 which Uwe Bulga sent to me? I will test your new version this evening. As I am using alevt since I think over 10 years, I hope that I can use this application again with vanilla kernels without reverse-patching!!! At the moment I am using 2.6.32.7 with a reverse patch Uwe sent to me... This works fine as before... Maybe 2.6.32.8 can correct the dvb-demux driver. The required monitoring demon MUST work independently from the external player application doing the tuning. My current script switches off and restarts alevt at every channel change, including waitstates so that the player application and alevt do not interfere when accessing the demux device (-timing issue) But that's just a very dirty workaround. I will have a look into alevt, why the update and eventhandling stops after changing transponder/provider... May be I can find something. The task is to change that behaviour. alevt-dvb should follow the new channel. In mtt (by Gerd Hoffmann @ bytesex.org - xawtv-4.0 pre) a module called dvb-monitor does that job. Cheers CS Thanks for your this version. You're welcome as every other user is. Emil Emil and others: Will you please use the appended version? I kicked out a nasty error message that printed out an error every time when alevt was entering a zero entry in the PAT. This error message wasn't even relevant for debug purposes, so I eliminated it. I dropped some lines about external dependencies in the README file. Some critical words on that one: http://linuxtv.org/hg/dvb-apps/rev/7de0663facd9 1. alevt-dvb is not a DVB-only application. It's core origin is to address analogue cards. Only within a rather incomplete patchset alevt can address DVB cards too. In so far that's a bad idea to put it into the dvb-apps. 2. With the exception of Christoph Pfister who has done a very good job with the latest kaffeine the personal scenery @ linuxtv.org is like a rat race in the production of appropriate drivers. Production and maintenance of applications is rather cemetary-like @ linuxtv.org, i. e. de facto not existing. It's for instance hihghly questionable why there are still 2 formats for a channels.conf file (vdr format and the reduced zap format). The zap format is obsolete IMHO. As the situation is as it is, this expectation at least sounds utmost naive and has got nothing to do with reality as it is: What about adding this program to v4l-dvb (under v4l2-apps/util/)? AFAIK, alevt currently doesn't have a proper site where development could take place. I think it would enjoy a better maintenance if it was hosted in vl4-dvb, and it could be an additional testing tool useful for drivers development. And it is GPL-licensed.

As long as there is not at least one person doing the necessary DVB maintenance sponsored by some industry there will never be a significant change at all. The roots of the DVB project were a company called Convergence media in Cologne, Germany. When this company broke down, the relevant persons vanished one by one leaving behind their heritage. For details ask the administrator of linuxtv.org, Johannes Stezenbach. 2. Right now the personnel of the DVB development appears and vanishes whenever they want to. It's completely absurd to build up a kernel branch nearly only on volunteers, but that's the way it is. Even Linus Torvalds does not see that there should be a change: Do everything to win skilled ans sponsored people for the work to be done. 3. I do not trust in the capabilities of the man who is maintaining the actual dvb-apps. His mouth is too big, his thoughts are malicious very often, his experience level is rather low, and his capabilities aren't even mediocre.

You need qualified people and, as a minimum adequate demand, at least one sponsored person if the job is not only a fun bringer but at least in significant parts a rather unthankful one. DVB development at linuxtv.org has been a stepchild for more than 5 years now. All the former significant people have vanished. As long as this continues we're on our own: It's us picking up the issues, it's us to investigate etc. We cannot continue to delegate issues in the traditional paternalistic spirit - at least not with these people. To get back to the program: I still do not comprehend why alevt-dvb hangs when the transponder is changed.

When you change the channel within the current transponder the program takes a short break and then comes back continuing to read the same PMT. It will not follow the external player doing the tuning to the new channel. 2. When you change the channel AND change the transponder the program will hang and will only get finished by _killall_.
