Interesting. I was not aware of that fact, and was under the assumption the vendors purchased the video chips and licensed the technology. Good to know!
EDIT: it looks like once again Cusa has quoted an incorrect price! the orginal link I posted is now 299.99. However the mailer they sent out must be honored, so it links to the 269.99 version still. If anyone wants this add I'll forward it to them. Just pm an email address, and I'll forward it.
