I am a little confused here too. I have seen a Sony Vaio Playing a BlueRay HD Video, same as i have seen a Tosh HD-DVD Player. I am sure that Sony will sell Blue-Ray drives for Laptops towards the end of the year, but i have to say i dont have enough knowledge to say if they will play a proper BlueRay HD Video (Pre-Recorded). I seen a demo, but this was a writeable duel layer BlueRay disk. I am sure that there must be a plan for Sony with them playing Video BlueRay disks as Sony PCS are entertainment PC's, there normally aimed at that. I wish i knew more about this subject, will read-up.
One more thing to say is, where will this all end? As i have seen an Apple MAC Playing back 2500 X 1600 of a TV Advert. Wallis and Gromit was made with an EOS 1-II 16.? Mega Pixel Camera. So in theory that can be played back at more or less 5000 x 3000.
There are not many about at the moment but a 1080 x 19?? screen is amazing (1920? cant remember) they are True HD. That Sony Camcorder you have is an amazing feat for the price. You cant get close to it without making your wallet at least 3k's lighter.
M$ Have a good HD section on there Windows Media Player Website, Got great footage of the Blue Angles and a heap of other planes like C130 With JATO Bottles, etc.
