So I guess in your case, there is still an issue with the compatibility
layer of http://jusst.de/hg/multiproto/ .
In my case I managed to get my cinergyT2 work with Reinhard's
modified vdr, with attached diff.

Manu said in an earlier thread that there should be compatibility with the old API so he doesn't think that should be a problem. The driver in the multiproto tree for my devices have not been changed so should work through the compatibility layer. The odd thing is that when I use an older pre-compiled VDR 1.4.x with the new multiproto drivers everything works fine but when I compile 1.5.12 with multiproto includes it doesn't work. ___ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr

Hi, Thanks for speaking with Marco, Reinhard - its appreciated. Unfortunately, the patch does not fix the problem. Still no picture on DVB-T transmissions.

Looks like the latter is true: Marco Schlüßler informed me that
the mapping of TransmissionModes in nit.c for DVB-T is wrong.
I've created the attached patch according to his' instructions.
Please give the patch a try and report success or failure.
Bye.

Hi, Morfsta schrieb: > This problem keeps coming up over again, but for some reason Reinhard > and Manu don't seem to want to talk about it. Well, what should I talk about it? I don't have a DVB-T device for testing and even if I had one, I live in a DVB-S only area in Germany. And furthermore, I was only involved in the multiproto development as a tester. I don't know much about the internals. The DVB-S2 port of VDR was contributed by Marco Schlüßler and I only redistribute it to protect users form the pain to merge two patchsets by hand. > I do not understand why you can't use DVB-T with DVB-S2 using the > multiproto drivers and VDR, but I doubt it can be much of a problem. Well, both Manu and Marco wrote that the current multiproto tree provides an emulation layer which allows to access drivers which only provide the old API via the new API. So it seems to me that either the emulation layer has a bug for DVB-T or the patched VDR passes incorrect data to the new API. > It would be great if someone could look into this for us!
