Please can anybody help with intermitant brightness increases or flashing during the capture of my anologue VHS home movies. The tapes play OK on viewing them on my TV, but transfering into my computer the picture on the monitor has brightness increases for 1 or 2 seconds, 2 or 3 times per minute.

I have a ATI AIW 30mb card, 1200 mhz processor. Capturing from TV is OK, and latest tapes are no problem, tapes 2yrs or older seem to have this capture problem, although as said all view OK when watched on normal TV on 2 VHS players used to try and capture...

Any help would be gratefull...........
