Guess no.1: pwcx (the binary module) isn't loaded/not working properly (maybe you have an older version?) Guess no.2: you need to set the framerate lower (if you set the framerate at 30, the driver won't let you change the resolution to more than 320x240). Nevermind what is written on the box, USB v1 can only do 640x480x15fps - and that is with some hefty compression going on. (the windows driver is doing software interpolation to get more). Guess no.3: maybe there is a problem with the "custom" kernel that comes with RH 7.3... get a vanilla one, recompile, see if your problem remains. As you can see, all I can do is guess, without more details... if all this fails, please provide more information - like a "lsmod" output, your pwc options from /etc/modules.conf, camstream version, gcc/glibc version, and so on.
