|Not heard that region settings have been dished (as per OtH suggestion) - but who knows; hopefully it is so? But presuming they haven't... then set it to your local area and leave it there. I'm not aware that you need to set it actually record a DVD; at least that was my experience with Matshata drive in an Acer Aspire... It recorded fine without a region set - but did require a region set to play disks...|
However the Panasonic/Mats---a series are a pain in the playback mode as their region settings cannot be overridden via software that will do just that; as in negate (by-pass) region settings on disks requiring a region other than that of the dvd-unit involved at the time... AnyDVD (Slysoft.com) is an excellent util to this end, and appears to work with "most" dvd-units... but not the Mats---a (and neither do any of the other similar utils....). AnyDVD effectively allows you to set your DVD unit region once and leave it there; then with that util installed/enabled you can play etc. any region disk without changing region settings on the dvd-unit. However - to re-iterate - if you were to have a Mats---a unit - either you change/replace it (it's possible to install a few others in its place - usually); or you set it your region and have an external dvd-unit (which will work with AnyDVD) and set that to a region of your preference?
The Slysoft util does get around nicely the max of five region sets/changes overall; set it once and leave/save the remaining four for real emergencies?
For example: I have an internal Mats---a set to region-2; and an external Liteon set to region-1 - and thus don't need AnyDVD for the most part. But if I do need to use AnyDVD then it works fine with the Liteon kit; and I can source/play any DVD with that, and then dub etc. to/via the Mats---a as region free (or any other) with other suitable software. Thus (apparently) confirming that region settings do not have an input when recording disks?
