Replying to Question about DV cameras

Every person I've spoken to has said that effective pixels are one of the important considerations when choosing a video camera. More = better picture quality. What I've found is that most cameras that take 1 or 2mp digital stills have a higher number of effective pixels than those that don't, cameras which seem identical otherwise. That is giving me the impression that the 'effective pixels' doesn't entirely refer to the VIDEO quality, which is all I care about.

I'm in Australia and the two models I'm looking at are Sonys. One has 400,000 effective pixels and the other has 690,000 effective pixels (but it takes 1mp stills which I really don't care about). Which of the below cameras would give better VIDEO quality (I hope they are the same then I can get the cheaper one).

It's the DCRTRV22 V the DCRTRV33. Those cameras seem pretty much the same otherwise.

Thanks in advance, hope that all made sense.
