	I just added modified the one line that sets
		dvb->vidmode = video_mode_NTSC  [dvb.c]
	and modified 
		static init mode = 1		  [saa7146_core.c]
	and for good measure
		mode = 1				  [Makefile]

	they may not have been nessecary, but I got them from previous
	posts about NTSC.

	The flickering is appearing on the monitor.  Using Tuxview, it
seems
	that every other line is missing.
