Intel's Montevina chipset is expected to put H.264 support into its graphics cores. Marketing people claim that now you can watch Blu-ray for three hours thanks to that, but I'm not so sure. H.264 support has been in graphics chips from nVidia and ATI (not sure if they were in the mobile editions, though) and yet I don't hear anything about battery savings in systems that have those. The graphics chip either has H.264 support or it doesn't; even if Intel has somehow optimized theirs I can't imagine that the energy savings would essentially triple the playtime over other solutions.

Even with the backlight turned all the way down, the processor and GPU can still eat up a massive amount of battery (even when clocked down) while watching from a CD/DVD. |

SSD/Hybrids won't make a massive difference in DVD playing yes that's true, but nearly every projection I've seen speculates 25% improved battery life for the sheer fact there are no motorized parts, even playing DVD's the HDD is accessed so there will be significant time gains. For the sheer fact it is motorised it instantly is a battery sucker. Plug in a 40gb USB powered hdd watch your battery life plummet, plug in a 32gb (biggest I have) USB thumbdrive and your lappie runs 10mins longer. Now that's with minimal activity. When there's constant access it's more like 20. Now granted that's a poor test, by using USB, but its fairly clear motorized vs non motorized is a non contest.
If you're saying to me the reduced power/higher performance cpu's aren't making a difference well I have a P4, a centrino and dual core laptop on hand that beg to say otherwise. CoreAVC is optimised software for h264 decoding vs ffdshow. Is that going to improve my battery life? Yeah it will by the sheer fact of the reduced cpu load, but really what will have have a longer battery life a p4 laptop running Coreavc vs a c2d laptop running FFDshow? I almost guarantee the C2d by a mile. Optimization helps but the hardware is becoming more energy efficient in light of he poor growth of battery tech. Nimh/LIon battery tech has barely seen any improvement in the last decade. It's a massive problem - it's one of the major issues with the development electric car. New engine designs is what keeps the forward momentum going.

I guess the only way to really keep the advantage of mobile tech is to use something like pimpstreamer and get the reading/decoding/resizing off the mobile device. But then again the mobile device will suck power via its connection to the streaming server. Can't win really.
