This one is obvious.

That is not too slow, it is a almost normal framerate. Normal video
usually uses 25 fps, but having 22-23 fps won't be a big difference.

MPEG-1 streaming is almost impossible, because it is not a streaming
format. It lacks the necessary headers that the client needs to
determine how to decode the video stream. VLS has no extra logic for
this. If you *want* to stream mpeg-1, then you can either:
1) convert it to *.ts by using VLC (or another tools)
2) use VLC for streaming that file.
