I am assuming that your region-free player does NOT convert PAL to NTSC, by the questions you have asked. I highly doubt that the Video Filter converts PAL to NTSC, it just removes the copy protection signal, allowing you to record a dub of a Region 2 disc that is copy protected. You will need a converter, if you want to record a NTSC disc from a PAL disc.
As I said, converters are expensive. For the price of most converters, you could buy a really good region-free, converting DVD player, like the Oppo 980. Or, much cheaper than a converter, a cheap converting DVD player that can be made region-free. Often, there is little or no mention of the converting abilities of cheap DVD players in their literature. Lots of cheap Toshibas and Philips players do convert. You can go to www.videohelp.com
, and click on "DVD Hacks" in the column on the left. Here you can find info to make these cheap players (and others) region-free.
addendum: when playing back a Region 2 disc, there is nothing in the signal that says "Region 2." That encoding on the disc is just read and used by the player, to decide whether to play the disc or not, it isn't passed along. Recording such a signal on a DVDR would produce a Region 0 disc.
