I can use xawtv fine for capturing images.
I just tried to capture a movie and it gives an error (I think I need that the -noxv option so I give that).
Same problem with or without the -noxv option.

Using the ov511-2.22 driver for my Creative WebCam Plus.

This is xawtv-3.88, running on Linux/i686 (2.4.21-pre5-ac1)

The program that Xawtv uses for video recording (streamer?) apparently doesn't support the YUV420 format that the ov511-2.22 driver outputs. No version of ov511 supports format 6 (15-bit TrueColor) or format 5 (32-bit TrueColor).

In order for this program to work with drivers such as ov511 or pwc, it will need to have YUV420-to-RGB conversion support added. The code to do that already exists somewhere in Xawtv, so it shouldn't be difficult to do. Someone with more free time than myself will need to do that, though.
