Have a .m2v file and a .ac3 file... How to put them to dvd?

[XRacerGT]

I was following a guide when I hit a wall. It got to where you import the m2v file and the ac3 file into DVD Maestro. However when I try to import the video it says

Media Not Supported Error (0xc10b0002)

Every time I load up Maestro it gives me this error which i just close and ignore:

Real Time Preview functionality will not be available because no decoders have been detected. (0x410a0011)

Is it just messed up? It imports the audio file fine just not the movie. Is there any other program to pull the m2v file and the ac3 file together in order to make a VIDEO_TS folder so i can make my movie?

thanks

lets multiplex them to an MP(e)G Shall we?
get urself TMPGEnc(look under TOOLS on this site)
FILE
MPEG TOOLS
SIMPLE MULTIPLEX
VIDEO INPUT => YOUR M2V FILE
AUDIO INPUT => YOUR AC3 File
TYP: You can choose there, but i suggest you use MPEG2 VBR(cuz it gives better quality )

Select an output file and hit the RUN button

from there on, follow guides from MP(E)G FILES to DVD
