I have problems playing MPEG2 files in v3.0.1 (i don't remember if the problem was there in previous versions also).
The problem is that from time to time I see some really bad blocking artifacts all over the screen.
It's interesting that if I remux the MPEG2 stream to from .mpg container to .mkv container the problem goes away, VLC plays the file perfectly, so the problem is not in the stream itself, just the container.
Here is a 8 seconds sample that reproduces the problem at 0:04:

Here is the same file remuxed to .mkv, which plays fine:
