Ok - problem solved. Here's what I did. It should be of use to other users of PDP with PWC-based webcams too.

188-247 and 488-489.
height. I don't think you'll need to change this but I only want to use 160x120.
My Logitech Quickcam Pro 4000 works like a dream now with the most recent reverse-engineered open source PWC driver (10.0.7a) from http://www.saillard.org/linux/pwc/
It seems like the problem was that PDP was using very specific features from the old pwc/pwcx driver that are no longer compatible with the new reverse-engineered driver. Is Tom still updating PDP? I think that this should be changed in the next release, or at least commented on in the readme.
Anyway, hope this helps some people.

Ok, I looked at installing the old PWC/PWCX driver last night. Only problem is that as the PWCX driver is closed-source, there are only versions for a couple of specific kernels. Unsurprisingly, 2.6.12 is not one of them. I can force the module to load even on this kenel (can't I?), but will it still work? I can try that.
But ideally, i'd like to get the camera working with the latest reverse-engineered drivers. I know very little about these things, but it makes sense to me that the problem lies in the fact that PDP forces the camera to run at 320x240 @27fps. I only want 160x120 @ 10/15 fps (I have a slow CPU and I want it to be doing lots of other things at the same time). Apparently, PDP has some "extra features" for webcams using PWC but as far as I can tell all it does is lock the camera to this resolution and frame rate...
I know nothing about c programming at all, but I'm considering poking around in the PDP source code and trying to disable all the PWC specfic stuff (by commenting it out?) and then recompiling. Is this a really stupid idea?! Probably.
Opinions on this approach would be appreciated before I try it!
Andrew.

Derek,
Thanks for the tip - that makes sense actually as I previously had the webcam working with PD when I was using a 2.4 kernel. I can't remember, but I suspect this was with the old PWC driver.
I'll try that this evening and report back!
Andrew.

Hi Andrew,
I've always had bad luck with the reverse-engineered PWC drivers + PDP. Perhaps you could try the USB-PWCX binary drivers from Phillips and see if they work better?

good luck, d.
