I've been struggling with glitches when I export rendered 720p HDV footage back to my HD1 camcorder from Premiere Pro via the MainconceptPro plugin's export facility.

I figured I must need a faster processor. But tonight I tried remuxing the rendered file using RemuxTS (available here: http://www.yamabe.org/soft/RemuxTS00229.zip ).

Remuxing only takes a few moments, and the remuxed files export PERFECTLY! Yippee!
