I am evaluating DMC to see if it will do what I need; which is the following:

I have DVDs I create in Avid Liquid that produce VOBs on my local hard-drive as well burn directly to DVD. The DVDs are created in NTSC format and I need to create DVD versions in PAL for viewers overseas, etc. So, ... my plan was to take the VOBs that were created in the directory VIDEO_TS (on my hard-drive) and convert them to PAL using DMC, and then burn them to DVD using Nero.

A typical VIDEO_TS folder will contain the following files:
VIDEO_TS.BUP
VIDEO_TS.IFO
VIDEO_TS.VOB
VTS_01_0.BUP
VTS_01_0.IFO
VTS_01_1.VOB
VTS_01_2.VOB
VTS_01_3.VOB

My plan was to create duplicate directory structure as above with VIDEO_TS on the root; except the VOBs will now be PAL instead of NTSC. Then I was going to burn the directory structure "VIDEO_TS" and everything under it to DVD.

Now, my questions are:

1. Does this seem like a feasible and consistent process?

2. After conversion, I noticed that the file extension is mpg as in "VTS_01_1.mpg" versus "VTS_01_1.VOB" Can I just change the extension after conversion?

3. Considering this scenario, do I need to burn via Nero as a "Data DVD" or "Video DVD?"

4. The other files under the VIDEO_TS directory don't have to be changed in anyway - right?

5. Are there any gotchas I may not be aware of?

Thanks in advance for your patience and help!
