I think for us who are less tech minded, youtube may be the best option. At least, if it isn't pulled from there for violating copyright laws (a recent judgement against youtube was meant to force them to remove copyright content as soon as it is reported).
Best to search for 'Transformers Animated', which will get you this link:
http://www.youtube.com/results?searc...rmers+animated

That will give you a heap of clips, including various commercial teasers.

But this person appears to have the entire premiere at the moment, in nine parts here:

Search for 'roll out' (the 3-part episode was called Transform and Roll Out), and you will find it.
