I've been trying to upload them since yesterday afternoon (I even left my computer on overnight) but for some reason, they keep cancelling and resetting.
Normally I have little trouble with Xtube Uploader; I just add the videos and they're online in a few hours. However, I might be having trouble since I'm trying to upload about 1 gigabyte of footage on a very slow internet connection.
I'm going to keep trying to upload these videos and if it absolutely comes to it, I'll compress the files (making the videos low quality) and upload them to the website directly.
I hope you enjoy the videos when they are online and that you forgive this hopefully minor delay.
