First off, thank you so much for your opinion.

I understand about the audio and the parts where there's no lip synch but the characters' mouths are moving...that all could have been fixed. But about the letterboxes...I wasn't sure whether I was better to leave them in, or cut them out. For some reason, I thought I was supposed to have them in there, to have a 4:3 ratio. The other way to do that would have been to cut off parts on the sides, and that didn't seem like a good idea. So you're saying it's okay to just leave it in 760x360 format (in my case)? I have no problem with that, I just wasn't sure what was best for me to do, haha.
Anyway, thanks again for the detailed reply, (and for the opinion!)...I really appreciate it! ^^
