Who here has seen both and what do you think? I've heard that the dvx is much better

What's the film look mode? 30P? 24P?

The XL1 doesn't have progressive scan CCDs. It uses a different method for capturing progressive. The DVX100 uses progressive scan CCDs. In 30P, both capture by skipping every 2nd frame, and this frame capture is then interlaced for VHS and S-video output. The big difference is that the DVX captures then interlaces, whereas the XL1 captures 2 fields at the same time (or almost the same time) and then uses interplolation to create a frame.
