Interesting. I assume you use the Nexus-CA or the Technotrend aquivalent? If I got Kein correctly, he is not using such a card, but a STB or something. I modified the dvb-kernel-driver to work with the CableStar2 (the DVB-C clone of the SkyStar2). I did not commit it to CVS yet, because it breaks support for the Nexus-CA. The problem is, with the current stv0297-driver the CableStar2 doesn't get a lock, but with my modifications (along with some beautifications) the Nexus-CA is failing. I haven't had the time yet, to figure out which stv0297-parameters are card-specific to fix it again. > I suspect some of the other register values are not treated correctly either, > since e.g. reading the BER values does not give meaningful results. > I don't have idea where to get the data sheets, I cannot correct those. I attached my current patch, which changes the flexcop-driver to support the CableStar2 and changes the stv0297 in order to work with it. It would be nice if you or someone else could have a look into it and maybe fix the Nexus-CA support. Please try to keep the beautifications :). Thanks in advance. Patrick.
