fast enough 4 ffdshow?

hi guys,

My pc works again yesterday after use some thermal componunt.

However, when it runs zoom player pro + ffdshow. It runs very un-smooth. I don't know why. I tried uncheck all the filter but it does works.

So, I uninstall the zoom player and ffdshow and dl the latest version. However, it still don't run very smooth when I use VMR9.

How can I fixed it?

Is it NVDVD codes is the best now? Should I replace it with my win DVD 6 codes?

Is theater trek 2.0 runs a lot better?

Finally, what is the best filter setting for my confi for ffdshow?

any tips is very much appreciated.

Thx in advance.
