Yeah, uh, for some odd reason, my iTunes refuses to upload certain videos onto the library, so I cannot get them onto my iPod. (Like, some music videos and clips can be uploaded no problem, others cannot)
I DO transfer them all to .mov format using XilSoft, but iTunes seems to pick and choose which files are worthy to be added. I'll be going to bed now, so feel free to post any questions you have for me; I'll reply tomorrow ASAP!
Thank you, everyone!
