Hi gang, if you can't laugh at yourself, off this planet!
I have a ? with advanced apologies if the section isn't right, but I tried...I chucked the Lost Season 5 Commecial DVD in my HP Vista Lappie and it spins up to the root menu, I can see Hurley microwaving a Burrito with all the options, but the "Play" button is absent? Doesn't matter which Player I use, Media Center Basic, DVDPLay etc
Only the stop and eject buttons work and I can't tag any buttons at all on the Lost menu. When I search for the disc on my C drive, it shows up as Audio and Video_TS files just as I would see when ripping a backup disc. The case is blue but it doesn't say BlueRay anywhere, not on the disc, the box set, nada!I can play older DVD's no sweat.
I couldn't find this answer anywhere, not even the Disney ABC site, please help me, I'm melting, meeelting, what a world, what a world...AAGGHHHH (kudos if you got that)Lord, I love to hate this hobby!
