As podcasts go this is very well produced, it stacks up against any major TV series documentaries in production values. I am not a professional astronomer, more an avid fan of the science so my remarks would be: greater science depth and more frequent episodes, which is a compliment. On a decent Cinema Display with a good video card they are gorgeous to watch.

You cannot play HD format podcasts on many iPods. I own a a newer iPod Nano which plays video beautifully but not HD.
You mention the versions of software you have but what kind of video card you have or display, that has a great deal more to do with your ability to play any video successfully.
Why is it necessary to refer to the narrator as a 'bimbo' ? Is this more to your own personal self loathing than women?
