Hi all,
Just wanted to thank you for your help and responses. As it was getting late last night, I signed off for the night and a classmate helped me this morning. I ended up using MPEG Streamclip, and she knew what the settings were supposed to be.
I’m sorry – I didn’t know there were beginner forums and I understand why this question would have been annoying to those of you who actually know what you are doing!
Thanks again for your help.
