Limitless switching between DVD regions on MacBook Pro?

Is there a safe way to remove the limit (6?) of DVD region switching on the MacBook Pro? I'm a multi-region kind of guy and this 'feature' dives me nuts. On the interwebs I see many 'tools' that scare me...

You can reflash the DVD drive's firmware to make it region-free,

I've used this on a Macbook Pro without any issue, but be cautious, and make triply sure you use the right firmware for your drive

Try using VLC to play DVD's, I believe it ignores region (although I don't have the means to check)

As mentioned, using VLC should let you get around the region limitations in software.

As far as the switching goes, that is a hardware-based limitation, and no, you can not change it.
