Hello I hope you can help me with this problem?

I have made an IAuthor subs manually, With the IAuthor programme, and the file name ends with PS and I can burn it in Nero, but
when I made it useing DVD2SVCD ver. 1.1.0 build 1 I got a IAuthor_Muxed_File0.MPS file, but on the log it was written:
D:\THE NEW DVD2SVCD TEST\I-Author\CD_Image_File_CD2.cif closing program
CD-Image creation finished. But I got no CD_Image_File_CD2.cif but that file was not created.
How can I burn the IAuthor_Muxed_File0.MPS file?

My second question is when I made a svcd and used svcd subtitles and in CD image I pressed dont make images.And I got a CD_Image_File_CD1.
Then I used daemon tool and burnt it with nero. I got the chapters but no subtitles.
Then I burned the bbMPEG_Muxed_File-subbed00.mpg and I got subtitles but no chapters. Why?

Thank you for your help in advance.
