Mixing TV/movie aspect ratios in Vegas and/or avisynth/Vdub

[obsessive24.livejournal.com]

I posted a short note on how to mix TV and movie widescreen aspect ratios. It's Windows, Vegas-centric with an option on avisynth/vdub. It's not exactly rocket science and I'm sure the techies are laughing because I've done it wrong somehow, but thought I'd drop the link in case it helps, like, anyone. :D
