Thats weird your Single 1.8 can't handle 720p h.264. My 1.67Ghz PowerBook G4 can... just. Possibly due to the fact mine has a very clean Tiger install (All it has is Logic Pro 7 and Final Cut Pro 5)... but Idve thought your 1.8 wouldve managed it.
It can just play it but some frames are dropped. I only consider a system capable if it can play a video without dropped frames and with at least 10% CPU to spare.
Other very possible factors:
-your 9700 GPU is both better than my 6200 and runs on an onboard AGP 4x vs my AGP 2x.
-10.4 vs. 10.5 would definitely make a difference in terms of 720p h.264. 10.5 taxes the GPU a lot more than 10.4 when core image support is there like both of our systems in question.
-system bus and memory are 67% faster in your PB
A 1.8GHz 7448 is certainly more powerful than a 1.67 7447 so the reasons above are what I would equate the differences to. A quick example.. my CPU score in xbench is as high as 96 yet my overall score has never been higher than 63. Geekbench score on my 1.8 is 1127.
