Be careful when re-syncing AV streams, since your own machine will introduce delays in both the video and audio pipelines, which must be corrected for in the editing software options using a known good stream before you try and fix a duff stream.
Thanks for the tip.
I used avidemux to shift the audio by 300ms and its watchable, albeit not perfect. However 300ms out was definitely not watchable.
Configuring avidemux by stopping the video, entering a new ms shift value, and restarting the video, is not at all ideal, but it's got me close enough for the time being.
