Grazie's right I've been using DVDA for a few years now and while I was encoding to Mpeg2 with DVDA3 I have found that DVDA4, at least in default, will rerender whether I import the video as AVI (format I capture from on my Panasonic GS500) or if I take an Mpeg2 render of my final video and import that.
So all that to say with the price of hard drives being as they are I'm rendering to AVI using Vegas then importing that AVI to my DVDA project then setting the bitrate in DVDA as high as it can go and still fit on the disk.
Anyone out there find a better way? If so please let me know cuz I'm always looking to improve the process.
I don't want to go on the cart!
