Hi everybody, within the current kernel concept you are forced to compile the dst and dst-ca modules and delete them afterwards if you enabled DVB_CORE_ATTACH. With this patch you optimize RAM usage for all bt8xx DVB-S abd DVB-T cards with the following known exceptions (please correct this list if one or more cards are missing): 1. Pinnacle PCTV Sat with CI extension 2. TwinHan DST and clones 3. TwinHan DST with CA slot 4. Chaintech DST-1000 5. DNTV Live ! Please acknowledge this only in connection with the bt8xx documentation fix (i. e. patch 1 / 2).

S.: My past attempts on that patch were based on the assumption that a Pinnacle PCTV Sat with CI extension can run with the modules combination dvb-bt8xx plus DST-CA. That assumption was wrong. My apologies for that. But this patch should be OK now. -- "Feel free" - 10 GB Mailbox, 100 FreeSMS/Monat ...
