Free software wise it isn't a problem and you can install the software needed
with/on Trisquel as described elsewhere. The problem is/was digital
restrictions. I forget if DVD boxes advertise this (I think they do) although
most commercial DVDs use CSS (digital restrictions). The problem is with the
US law. In the US thee is something called the digital millennium copyright
act. It makes bypassing digital restrictions or informing others how to do so
illegal.
I tend to suggest avoiding technlogy with digital restrictions. Be it online
entertainment that use things like silverlight/adobe flash or CPUs that are
enablers. It's less of an issue because the technology is broken in this case
although it probably shouldn't matter. You should probably still avoid it.
We don't ship blu-ray drives for a few reasons. One the technology is dead.
But two because we (I'm talking about ThinkPenguin) would rather not endorse
digital restrictions. Especially when the technology doesn't work well on
GNU/Linux or work well with free software.
