I have bee making AV's using two projectors ets for about 20years. Have recently purchased the latest version 4.44 of PTE and am ok producing fade and dissolve but am completely lost with how to add sound. Can someone walk me through the basics, how do I introduce audio via my computer, how do I know where the beginning and end of a piece is, how do I set the length of music to match the pics etc etc. etc. Your help will greatly assist one who is confused. I am based in the UK. Gilbert Jones
