After searching the mailing list several times I am still confused about the actual setup required for this card, i.e. whether the option for bttv has to be "card=0x68" or "card=0x71". Vision DTV Ter 3021, Tuner bears a sticker with "6k08PT1", and there is an NXT6000 inside the metal can. pci bus 0x0000 cardnum 0x0e function 0x00: vendor 0x109e device 0x036e Brooktree Corporation Bt878 Video Capture CardVendor 0x1822 card 0x0001 (Card unknown) pci bus 0x0000 cardnum 0x0e function 0x01: vendor 0x109e device 0x0878 Brooktree Corporation Bt878 Audio Capture CardVendor 0x1822 card 0x0001 (Card unknown) http://www.linuxtv.org/wiki/index.php/Supported_DVB_cards#TwinHan_V3021 suggests it should be similar to Nebula DigiTV, therefore for bttv the correct option should be "card=0x68". But his lead to complete freeze of the system (even after applying the freeze and the timeout patches, kernel is 2.6.11). With autodetection and with "card=0x71" it seems to be initialized correctly (but only *after* applying the freeze and the timeout patches), although as a Twinhan *DST* Aug 2 20:27:48 montel kernel: bttv: driver version 0.9.15 loaded Aug 2 20:27:48 montel kernel: bttv: using 8 buffers with 2080k (520 pages) each for capture Aug 2 20:27:48 montel kernel: bttv: Bt8xx card found (0).
