Do you really believe what shops are saying about the quality of a board? In times where even popular computer magazines (at least here in Germany) compare the quality of DVB hardware with the bundled (third party) software, I think it gets really hard for the user to make the right decision. > Maybe this is then not valid? Can it be used with QAM 128 when > running your version of the drivers? Anyway: Yes. I had the chance to fix the QAM128 support for the Cablestar2 ssh'ing a to a PC of a Finish user who wanted to use QAM128 and it worked after disabling corner detection. The cablestar is not supported in current dvb-kernel CVS, but only in the archive downloadable from my website. I really would love to have the support for it in dvb-kernel, but I don't have time to include the change to dvb-kernel currently and I don't have the other stv0297-based cards to test compatibility. Maybe then QAM128 would work correctly even for the TT stv0297-based cards. regards, Patrick. -- Mail: patrick.boettcher@xxxxxxx WWW: http://www.wi-bw.tfh-wildau.de/~pboettch/
