Switching from Adobe, Technical question about mpeg workflow

[digikey1234]

So I was using APE3 (Adobe Premiere Elements 3.0) and basically I got tired of all the tweaking and waiting time that it takes for any of my projects, I use a HDD JVC Camera (HDD stands for Hard Disc Drive) it produces files in mpeg format. My problem was that APE3 is designed to use the AVI format it supports mpeg BUT what it actually does is convert (decode) from mpeg to AVI to VOB (for dvd burning) that's why a 1.5 hr project could take up to 6 hours, plus all the tweaking of the field order, adjusting footprint, etc (some APE3 user will know what I'm talking about) , by the way I love the way VS10 automatically identifies the media field order and change it to match the project. So I found VS10 much easier to use, it supports my MOD files from my camera, good editing option, exactly what i needed, BUT, I am still not sure about the time length to decode and burn a dvd.. I was under the impression that VS10 works directly with the mpeg (natively supports mpeg for the background workflow) format so there is no conversion to AVI (as APE3) but it is too slow, is like 1.5 times the total length of the project, so it looks to me that is in fact doing something else and not directly converting from mpeg to vob. I can use as a reference Sonic My DVD I know for a fact that the whole workflow is in mpeg so the decoding process is a fraction of the project length... there is no other conversion/decoding involved
Can someone confirm this?

PS I have a double core CPU with lots of space.. no issue here...

On the Create Disc screen there is a check-box that says Do Not Convert Compliant MPEG Files. If that box is not checked, Video Studio will follow "your instructions" and re-code the MPEG to match your project properties.

If the Do Not convert box is checked, and if Video Studio agrees that the file is DVD-compliant, it should go more quickly. Most of the time my video is compliant, but my audio needs to be converted. This usually takes 10-15 minutes. (I usually use Ulead DVD Workshop, and it may be slightly different.)

It also depends on the type of editing you do. for example, if you apply a color-adjustment filter to the entire video, the whole file will have to be re-coded, and this is going to take some time.

Making sure SmartRender is activated in VS should also speed things up. Be aware, though, that for some people, SmartRender can cause more problems that it resolves.

Thanks for your comments you answered my question.. it make sense now.
