In my last post, I mentioned briefly that I had yet to get DVD playback to work despite trying every solution out there. It turns out it was something as simple as the region not being set on the DVD player. I bumped into this while doing a few things in Vista.
Now, after a quick search I have found what appears to be the solution to this on the Ubuntu side. I haven’t tried it since the region was set on Vista but if you have similar problems, give this a shot, especially on a new computer.
