DVD intro different than TV intro?

I watched it on Youtube; technically the intro is the same but yeah, the Kid Rock theme was cut in favor af a more rock-style version of the closing credits theme. Shame because I'm not a fan of Kid Rock really but that song kicked @$$! All I could think of was the Married with Children DVDs; Seasons 3+ have a retarded new theme instead of the Frank Sinatra one and have no features at all (S1 has a reunion special but still). The Stripperella DVD technically has had better treatment (people claim it's widescreen even though the box says fullscreen) and as discussed the Kid Rock theme was removed. DAMNIT!!! It seems like every time I find a show I really like it gets cancelled and/or has bad DVDs! Lucky Louie I loved but at least that DVD (which I own) is decent (would have liked more commentary's though). Anyway, shame about the intro but at least the replacement is somewhat cool where as Married with Children DVD replacement theme sucks completely. Hopefully I will get the Stripperella DVD soon...I havn't seen all the episodes.
