Hi. I just built a new pc for encoding.

My old pc setup was:
p3-500/256ram/premiere6.01/Avisynthv1031_and_pluginv028beta37_premiere/TMPGENC-0.11.26.110_newer12H
My new one is :
p4-2.26(533)/512 pc1066/premiere6.01/Avisynthv1031_and_pluginv028beta37_premiere/TMPGEnc-2.56.39.143-Free

I couldn't get the latest PremiereVideoServerPluginv093+Avisynthv106 to work, so I reverted to what I used prior. I read about the DirectShow stuff here and at videotools.net; that didn't help me. Another kicker is that I didn't like the pop-up asking for registration.

Question: Am I short-changing myself by using the older avisynth? If so, how badly? Speed and Quality matter to me, but I realize sometimes theoretical differences don't translate to practical ones.

Thanks for the help.
