Watch out when you upgrade to the new Production Studio. I just did and I also have the Matrox RTX100. The Matrox tools do not work with the new Adobe Production Studio right now. Matrox has a statement on their website indicating they are “working” on it. Also, your external NTSC monitor won’t work (in the new Production Studio) while you’re editing video (I don’t know about PAL if you’re using that in the UK). I’d stick with Premiere Pro 6.5 until Matrox fixes its incompatibility or Adobe comes up with the patch.
