- Remove $Id CVS logs for V4L files - Included newer cards. - Added a new NEC protocol for ir based on pulse distance. - Enable ATSC support for DViCO FusionHDTV5 Gold. - Added tuner LG NTSC (TALN mini series). - Fixed tea5767 autodetection. - Resolve more tuner types. - Commented debug function removed from mainstream. - Remove comments from mainstream. Still on development tree. - linux/version dependencies removed. - BTSC Lang1 now is set to auto_stereo mode. - New tuner standby API. - i2c-core.c uses hexadecimal for the i2c address, so it should stay consistent.
