Do you get an error when you load more than 100 photos? I don’t have version 8 anymore and I am not sure if there was an error.
I have version 9 and 10 installed and I just loaded in 132 pictures, no message other than adjust for ratio and resolution.
I know that VCD and SVCD would have a limitation of 99, since CD can only have 99 tracks. work around if you can break the projects into smaller sizes you could load let say 1 to 90 pictures, add in the transitions you want and export that out as MPEG-2 file. You then can repeat that however many times you need to complete all the photos.
Once those are done, you can start a new project and load in each one of the MPEG-2 files, add in the transition between them then burn that to disc.
