Thanks for the informative response. Thru following Apple's instructions for completely uninstalling its i-apps, then reinstalling 'fresh', as well as installing the K-Lite codecs, I was able to get my system to work, albeit with a little jerky video on ABC, but that was probably more their quality issue than mine.
I do appreciate your input on iTunes, however, because I was just 'biting the bullet' to learn it because it goes with iPhone. If I don't have to use it, I would rather not. The only problem is that they have changed WMP so much that I don't like that much better.
So, I will take your advice and try the VLC Media Player.
Take good care,
