I love the podcast. But umm. It’s becoming the time machine/drobo show. Guys?


DVD regions.  You were partly wrong about this.  You *can* change or play DVD regions as many times as you want in software (vla VLC or whatever) if, and only if, your drive behaves as a RPC1 drive.  All drives since 2000 are now RPC2 where the drive itself contains the number of swicthes between regions.  Once you hit 5, you need to get a new drive (or re-flash the ROM).  The version of VLC does not matter.

When I got my macbook (Core duo) it came with a UJ-865 (RPC 2) drive which I could only change a maximum of 5 times.  After that, it wouldn’t change again.  I managed to find on the web a site that contained a version of the ROM for this drive which converted it to RPC1.  I now can play and switch between regions to my heart’s content.
However, this is not for the faint of heart.  Things may go wrong and then you’re “SOL”.  The easiest/safest way to get around this problem is, unfortunately, to by a simple USB DVD ROM and use that one for R1 playback and the internal one for R2.
