Need advanced help with making a rip

[DC_Rocks!]

OK, here's the deal.

I have a DC connected to my PC with a crossover cable using a BBA.

I have successfully copied all of the files from the original game disc to my PC. I'm in the process of downsampling the audio and video to fit to a regular disc.

Now, here's the dilemma. I'm not real clear on the next steps and I can't figure out why I can't view the contents of the original ISO images with ISOBuster or WinISO. I can extract everything from them using extract.exe.

Any help with finishing up the work is greatly appreciated.

Thanks in advance.
