Hi,
A bit off-topic, but do you use the now decommisioned Windows Moviemaker for editing? Ask because i did, and started to suffer from some high pitched creaking sounds, distorting the original sound...which i experience in your movies as well. Might just be my computers, but doubt it since i use 3 different ones here. (I´ve since switched to the free "Videopad Video Editor from NCH, which is somewhat similar to Moviemaker as far as "ease of use" goes, and doesn´t have that unfortunate effect on the soundtrack).Sorry to bother you is this the one you suggest?
