how do i burn these to different files to the same project. Sorry if you've answered this 100 times but i'm not familiar with this website
3 options: Re-encode one file to match the other. Use DGPulldown on one file to match the other (this won't change the AR though). Use an advanced authoring software such as DVDLab, and put each video into it's own VTS, then pray that your player can handle it.
