The actual version of the card in circulation uses the Thomson DTT7612 ... You do not need a patch to correct this on your machine, at least not for analog NTSC mode. Just load your driver as follows: modprobe cx88xx tuner=60 (it will use tuner 52 by default) modprobe cx8800 Tuner #52 is the previous tuner defined for this card, DTT7610, and tuner #60 is configured for Thomson DTT 7611 7611A 7612 7613 7613A 7614 7615 7615A The configuration for this card has been fixed in the v4l-dvb mercurial tree as of this morning. To update your v4l/dvb modules (so long as you are running kernel 2.6.12 or later) follow the directions here: http://linuxtv.org/repo/ I hope this helps, Michael Krufky
