According to my maths you only get 65 mins if you max out the bandwidth

allocation (9.6Mb/s, 37.6Gb/disk).
However you get 135 mins with stereo 24/96.

Yeah, some of the surround mixes I've heard recently aren't exactly

wonderful either. Personally I find wiring up surround speakers too much

of a pain, I used to have a 5.1 setup in my lounge, but I didn't bother

putting it back last time I moved as I couldnt face all the wiring.
Some random facts that seem relevant:
That are on the order of 100 DVD-Audio disks for sale in the UK (dunno

which are MLP or PCM), prices are the same as CDs. A DVD-A capable player

costs about EUR100, most cheap ones cant play DVD-A.
I cant find a public spec for DVD-A online, but the combination of a bit

of reverse engineering, a DVD-RW friendly player, and what stuff is

available (manufactures tech FAQs etc.) should make it a fun project :)
