[mythtv-users] Separate frontend vs backend question..

James,

Thanks for the info.

Actually when I was talking about moving the haup 350 into the frontend it
would make the frontend into a frontend/backend with only the storage being
behind the scenes.  Then again that doesn't benefit me much as you
mentioned.

I was mainly concerned with delay for LiveTV coming across the wire.  Now I
just need to find a very small, quite, cheap, nice sound and video only
frontend box that will actually run fedora or something..

-Matt

Yes. This is a primary function of separating the frontend and backend. A
100Mbit network is quite acceptable in performance.

It's kind of a waste to put a PVR350 in a frontend-only machine. I'd choose
some other TV-out solution if you won't be using the capture abilities of
the 350 card. The 350 makes much more sense in a combined backend/frontend
machine.

Why bother using NFS if you don't have a convenient NFS fileserver? If you
have a windows fileserver that presumably uses SMB, just use that. A Linux
backend machine can connect to windows fileshares perfectly fine using
Samba.
