Original cartoon soundtracks for DVD

[Patrick McCart]

Since many films put on DVD utilize surround audio tracks...and I was wondering something:

Do the original recordings for dialog, music, and sound effects still exist for the WB cartoons (and any others)?

They could be digitally remixed for DVD..which would improve the fidelity of the sound and expand it (But I'd like to have the original mono track on the disc along with the remix)

I don't know about voices and sound effects, but most (at least I assume MOST) of Carl Stalling's music scores are still in vault #16, according to and judging from the two Carl Stalling Project CDs. Milt Franklyn's scores, too, maybe? Mmmmmmmm..could be!
