Please assit in burning backup od "Undying" and "Desperados".

[liord]

Hi,
I have these two games and I want to make a fully functional backup from them (with no needed crack...). I have a Plextor 1610A burner with firmware 1.02 version and DMA setting set to off.
I have tried burning both games with CloneCD on speed 1X but it failed to read. Maybe it is because I checked the read sub channel data i don't know.
Please, advise me how to burn these games with their exact settings and which program can do the job for me. If possible please give me a link to that program. I currently have Clony, CloneCD, Nero, FireBurnner.
Also I would like to know, when burning CD's is it better to burn CD to CD or make an image first??

Thank-you very much!
