I worked on this format some days ago (there is a thread here viewtopic.php?f=21&t=3899) but there are some fields missing or that require additional checks/reversing mainly in the part regarding the chunks of compressed data because the rest should be complete.
for reference (it works for the first files till encounters one of the those chunks wrongly compressed, so final users stay far away from this) I post my quickbms script written till now:

What program are you using to extract the xbox360 iso ? Also the script don't work for the demo files 
Re: James Cameron Avatar .pak

Try WXripper for 360 iso's.
