It depends on what the original video resolution is.
If the original is SD and the machine is decent 3.2GhzP4/2GhzAMD or a single
core from any of the dual core machines, then it will take less than 1/2 of a
cpu, and won't affect anything on the backend. If the original is 1080i or
720p things get more demanding-If you backend has hardware encoders I have not
seen vlc interfere with recording, if your backend has software encoding in
mythtv then things get messy, or if you are trying to support multiple mvpmc's
with a single backend without have multi-core things would get messy, or if
something is using massive amounts of cpu time on the vlc machine things start
You can put vlc on anything that has file access to the files, so the machine
running vlc does not even need to be an actual backend. I have used a backend
machine and I have used a non-backend, neither has caused any issues on the
backend or on the desktop machine being used.
