Hello Assault Freak. No, there actually isn't a way to sead torrents yourself, because since you don't have the rest of the program downloaded, then you can't sead, can you? Seads are people that have the whole torrent already downloaded and are uploading it to the rest.
As for the whole burning DVD's thing, here's a way, and yes, I've tried it. Archives that are in parts only need you to open the first part and extract that. The rest are automatically extracted with it, and then once it's all extracted you can burn the DVD. As for opening the .NFO file, what you need to do is change the extenssion to .txt and then open it in notepad. You might see some strange stuff at the top, just skip down until you find English.
I hope this helps.
Regards, Albano.
