800MHz Athlon ThunderBird. The mpeg2enc was build on this machine so (hopefully) it is tuned for the Athlon's processor features. I did see mention of MMX being used during the startup of mpeg2enc. > Speeds *that* low would imply something > without multimedia acceleration. I.e. a pre-MMX x86 CPU or non-AltiVec > PowerPC. Nope.

Cost in quality should be zero (given the right material). The material is (going to usually be) interlaced as this is television broadcast. b. -- Brian J. Murrell
