Not really up on pc's but will have a go with the little knowledge I have. On the last pc I used it had a CD-RW/DVD drive combined, don't think it's the drives that come region free but the playback software you use, I could go into the properties then clicked on the file that enabled you to select regions 1-6, some will only let you change a certain amount of times then locks on your last selection. This was easily overcome as all I use to do was unistall it and as it was on a smart restore disc I just use to re-install. Don't know if this is rubbish to you or it will help.
