Are you using a registered copy of PTE 4.20? Yes Al, I do. When you are previewing the synched show, do you hear the whole selection, even though PTE only shows "1.31"? Everything plays well(music/pictures) IF is synched to 1min31sec that PTE shows. But I want to be able to put slides passing the 1.31m which I do not have a choice right now. Do you have more slides in the "slide list" (the one on the right-hand side of the main PTE window) than you are able to add on the timeline? I am using around 36 slides but I want to add a few more if I get all the music to play. Al you may be right. It sounds like there may be a problem with the .mp3 file. I am start to think this too. I just played the music in windows player it does play all the 4 minutes great but I tryed to put the music on cd just to check if I put it on PTE trough the cd and the CD like PTE plays only 1min31sec. Jeee! this is so strange??? Plays it all in one program(windows player) but not on the burned cd and PTE???do you have any idea what's going on? If you like you can send me your PTE file and I will have a look at it. If the whole package is not more than a couple of Mb, you can email it to me at al@alrobinson.com. If the show is larger than this, then just email the ".pte" file (no photos or music). Or the .pte file with photos and a url to where you downloaded the music, provided it is a free download. I bought the music from musicbakery.com Thank you so much for trying to figure this out for me. I may send you a PM first before I send the file.
