error after 9 hours rendering....

[Teddyberin]

hi, I am already 3 weeks busy with making a DVD of my holiday pictures and video (mpg). I am using MF 3 and an old PC so that's understandable why the rendering took so long. After rendering it took for my first (and only) DVD some minutes to burn. After this succesfull first burn it never works again.... HELP..... I get an error dat there is an error in module umfdiscbase.dll on 017f:064cf534
Meanwhile (after 3 weeks) I am desperate, I would be very pleased when I can show my pics now to my friends....
Who's got the answer?
Thanks in advance fo your help!!!!!!
