[AG-DEV] Vic Video Device Conflicts

With the AG 3.2 RPMs was bundling an AG 3.1 version of VideoProducerH264 & VideoConsumerH264 and wasn't bundling any VideoServiceH264.

I've put up new AG 3.2 RPMs with the latest H264 services and are available here:

You might like to try forcing the bttv device to be /dev/video1 in /etc/modules.conf, e.g:
  options bttv video_nr=1

for your webcam, try a modinfo on it's kernel module, hopefully it has either a index or video_nr param.
