I have noticed that the music on there is similar to what they put on DVD. is there any reason for this? I like the original tracks better!

I don't know. I almost wonder if they are showing it straight from the DVDs. Last night's opening and closing were posted by someone on YouTube:

Hmmm, that seems weird. It should be this one instead (http://www.youtube.com/watch?v=oTRY0KNpTg8) right?

Could someone give me a recap on how the HUB has handled the show's intros overall for each season? I don't get the channel and am interested to know.

I don't have it either, but that same person uploaded Season 2 credits from the Hub with Rock Around the Clock the next day:

It came from the episode Wish Upon a Star which was also uploaded in full and has the closing, and from what I see, on Wish Upon a Star, it has the original Paramount logo that I've seen before at the end, but on ROTC that replaced the theme with Happy Days, it had the new CBS Paramount logo from the DVD, so I honestly think they are showing some of the episodes straight from the DVD. I don't know why they are doing this.

I have watched every episode on the Hub and I think that ROTC was the only one that used the CBS Paramount DVD version there may have been 1 or 2 more that had that but thats about it. 99% of them have original music and openings.
