Have you already ruled out using a more suitable solution like a
videophone or IP cam with audio input, which will sync things up much

Will you be recording from the camera 24/7 even if no-one is on the
phone? If you are not, I don't think using MythTV's core recording
functionality is the best solution for your project. As Brad
suggested, using ZoneMinder - perhaps with an audio-supported IP
camera, will likely give you the best overall result if you want to
use MythTV.

Will you be keeping the recordings of all calls?

When you see what a 0.5s delay looks like, I doubt you'll be dancing
with joy. I find a small disparity in sync much worse than a larger,
more obvious difference.
