* - Patch was submitted by Hal Finkel to fix the problem with the tuner not working under kernel 2.6.7.
* - Changed usbvision_muxsel to address the problem with black & white s-video output for NT1004 devices with saa7114 video decoder. Thanks to Emmanuel for the patch and testing.
* - Fixed up SECAM devices which could not properly output video. Changes to usbmuxsel. Thanks to Emmanuel for the patch and everyone with a SECAM device which help test.
* - Removed some commented out code. Clean up.
- * - Tried to fix up the annoying empty directories in the sourceforge.net cvs. Fuck it up again. 8*(
