So I installed version 2.4.0, after uninstalling 2.3.4.

Burnt 2 DVDs, neither of which my DVD player recognizes.

Then I uninstalled it and reinstalled 2.3.4.

Now the CPU usage immediately jumps to 100% and the program hangs without even finishing the Avisynth frameserve check.

NOT impressed, guy ... I really liked the old version when it worked.
