not sure what you mean at source? oh hang on do you mean view it directly at youtube? yes I can, but when linked to the GM site it is 'seen' by pc users but not ipad (or not mine anyway)
It used to be the case that the iPad did not support Flash (not sure if that is still the case, haven't really kept abreast of iPad development). If it is, then that would be most likely the problem. While the YouTube site isn't Flash based the embedded video container of YouTube originated content is.
