I burn the CD, but then it acts like it has no data

I downloaded Knoppix 3.3 (11/03/2003) but now I can't burn it to a CD using burning image. I've used Nero 5.5.9.9 (also I've downloaded a patch, but I found out taht it was made for version 5.5.10), ISO recorder, ISOBuster,... and a lot of CD's!!! I can burn the image .iso, the program (Nero, ISORecorder and ISOBuster) tells me that it has been finished successfully. But whenever I try to boot the CD my PC don't run it. The boot sequence is A:, CDROm and HD; it reads the CD but goes on with HD (like the CD were a blank CD). when I try to access to the CD with Windows XP I can't, the error says

The CD ain't formatted
Windows can't read this CD. Maybe it's damaged or it is using a format the Windows doesn't know.

The .iso file is 733.337.600 bytes (699 Mb) and I've checked it with md5, it's OK.

Anyone can tell me what can I do?? I'm losing my mind!!!!

P.S.: Sorry for my English, I hope you could understand it
