I must admit ,I haven't heard of a conroe chip ,but I started off video editing on a AMD 1.4 gig processor with no problems whatsoever using Pinnacle 9 . I have since upgraded to a AMD 2gig and AMD 2.8gig [I now have two standalone PC's for editing ] My Pinnacle 9 only cost £29.00 from *C*orld .I think I may have mentioned in the past ,my editing PC's are not net connected and have no AV/spyware programs running hence nothing to interupt the data flow .I get no dropped frames or poor DVD's , it makes one hell of a difference .
