[HELP] MPEG 2 + AVI Video Files cannot encode

[Selur]

Okay, main problem: Hybrid doesn't support Windows 7 for ages and you are using an old version.
I don't support old version, that said:

For the avi: the Error message says it all:

Format pcm is not allowed for mp4 output!

=> either convert the audio or use a container that support your streams.

For the mpeg2:

y4m [error]: bad sequence header magic

indicates that something with the Vapoursynth script.
The Vapoursynth preview should probably show a more detailed error message.
To me the Vapoursynth script looks fine:

clip.set_output()

Only strange thing is that LWLibavSource is used as decoder.
Normally, DGSource is used for as source filter for mpeg input.
(does it make a difference if you change the ending from 'MPG' to 'mpg'?)
