Forget that, just put the (80s) TV show on DVD (and I don't mean the "extras" on the other DVDs - I want full-on season sets).
The ALVIIIIIIIIN collection was a start.... but consider how much it cost for as many cartoons that had been on it. They have huge blocks as far as music rights are concerned, and I don't think those will be easy hurdles to overcome. I still don't know why they haven't looked into the Alvin Show (as most, if not all of the songs were originals or public Domain), as that one would be easier to release. I find it funny that they think only the 1980's looking Chipmunks are most marketable, yet I have mainly seen 1950's style chipmunks on every piece of Alvin merchandise since the 90's (with the exception of a couple buttons, one featured the Chipettes, the other featured Simon with the caption "I Love Nerds").
But I did know of the "Thanksgiving" special and the Halloween one due to Buena Vista's releases in the 1990's. Especially when they were cleared out to bargain chains in the late 90's/ early 00's (as were a lot of TV shows that Disney owned like Ducktales or had deals to release like part of DIC's catellogue).
Thanksgiving in quotations, since it technically isn't about Thanksgiving. The relatives are invited to watch a school play. And the Chipmunks had to switch jobs... Simon had to act, Theodore had to do special effects, and Alvin had to do costumes. And before you say, "Sure, Alvin and Theo have valid concerns about their jobs, but Simon's on stage all the time." he's just not used to acting. It's a nice little special. it even opens up with an old song that the real Dave Seville wrote BEFORE Chipmunks... and even before Witch Doctor.
