YouTube video can be encapsulated H.264, On2 VP6, or the older
Sorenson Spark. So it's important to try to test the same file.
Where you are coming from appears to differ from where I am coming
from. I am looking at the XO from the point of view of "How usable
is this?" That question does not necessarily involve precise
measurement -- evaluation ought to suffice.
In my mind I did not volunteer to be a formal "tester". If you want
me to be, please publish a formal *specification* consisting of
'shalls' -- i.e., the XO __shall__ properly render H.264 videos, the
XO __shall__ without visual aberrations play back videos using an
on-screen picture size of at least 14.67 cm by 11 cm, etc., etc.
*Then* I will develop a "test suite", which I will run against every
new beta that comes along (to "check off" which 'shalls' are being
met).
