hi marc,
as chris explained, this is a problem with colour spaces. pdp_v4l tries 3 capture modes and uses the first one that is reported to work.
i cannot remember the exact model, but i have bought one of those philips webcams too for an installation and since there was only one single colour-space supported i have written the conversion-routines from yuv420p (i think that was it) to YUV422/RGB(A)/grey (the last of which was very easy ;-)). it should be in the CVS-version of Gem (GemPixUtil.cpp: fromYV12(char*yuvdata); YV12 is the FOURCC-name of yuv420p)
