Is there any software (preferably open source if there's a choice) which will allow me to join several .VOB files from a DVD into one? And before anyone asks no I'm not taking them from copyrighted DVDs or anything like that. I understand I could use something like Handbrake to rip to another format but I wanted to give AVIVO a try for the transcoding since it works well with VOBs and it's pretty quick too!
