DVD burning problem.

[tribal]

I had convert a movie from rmvb format to avi format.The movie contain 2 parts.(example: CD1 and CD2 for 1 complete movie) Then i convert the avi file to DVD.When it complete convert,CD1 got 1 folder which contain audio TS file and Video TS file and the same goes for CD2 when i finished converting.
The question is how do i burn this 2 files into the DVD-R using Nero 6.I had try adding this 2 files into the DVD-R but it prompt me that it can't because i think it's contain the same name folder and file.i had try rename it and it still can't.
Can someone out there please advise me how to make it work.

Open CD1.avi in VirtualDub. Set both video and audio to Direct Stream copy. Then File - Append segment, and add CD2.avi. File - save as. Give a name to your new only1CD.avi.
Process to DVD.
