Query: Good collection, but...

This is a nice collection of episodes that I can recommend to all Chipmunk fans (but personally I would like to have the episode "Grounded Chipmunk" included). But there are some quirks though: There are no title cards, making the episodes start abruptly after the theme song. But for some wierd reason, the very last episode on Disc 2, "Cadet's Regrets", have the title card intact. Every episode starts with the theme song, but they have used the older opening (with Alvin surfing in the bathtub etc.) through the whole collection, even on newer episodes which originally had the "white limousine" opening. The cover also states that some music have been changed, but I couldn't spot the changes (as opposed to the very blatant change of "Love Potion #9" to "Witch Doctor" on the Chipmunks Valentines DVD). Quality of sound and picture was acceptable.
