Correct, 10 points
Actually I was using it to install Server 2012 on the N54L as I couldn't be bothered fitting an optical drive just for a one off install, the 360 HDDVD drive is my "go to" external drive for around the facility, it plays pretty much any DVD and has a built in USB hub which is useful as some of the machines have limited USB outlets (but if you were interested in using it to backup HD-DVD movies yes you could as it plays them fine on the PC).
Bluray the optical technology is great, 25-50GB plus on a £1 disc is great for backup purposes (though not as useful as in the DVD/CD eras obviously). However Bluray the video media is garbage, its essentially the Betamax of the last format war, Sony basically took the position that the disc was 5x the size of a DVD so they would just make the file size of the video 4-5x to hell with optimization. By comparison HD-DVD could do equal video performance using 1/3 the space due to the vastly superior codec. Instead of Sony using its wallet to swing the format war in favour of the inferior format they should have just forced a collaboration and used BR as the optical medium and used the HD-DVD codec (or another decent one), then you would have been able to have every LoTR film on a single disc, but alas the road not taken.
