you talk about having no luck with burning cd's, but it has very little to do with luck. First you have to download the .iso file and check it against the md5 sum. In Windows download the free program "imgburn" and use that to burn the .iso, and burn it at the lowest speed that you can.
Once the disc is burnt have a look at it in Windows and you should see some files. If you can only see the .iso then you have not burned it correctly.
Another main cause for bad burns is rubbish quality blank cd's and dvd's

You will probably find out like I did that the media you are using comes in the third catagory of "landfill". My two makes were "Tesco" and "Kodak". Both now dumped in the rubbish bin.
The very best disc's that you can purchase are made by "Taiyo Yuden", but even with these you will have to be careful as there are a lot of fakes about. I purchased mine online fromhttp://svp.co.uk/
