In case anyone else should run into this problem, I thought I would post it here. It took me a lot of Google searches to realize my mistake. The default hostname for Fedora Core is locahost.localdomain. I basically didn't bother to change that on my Mythbackend and then I was trying to run a remote frontend on my laptop and I kept getting an error that /video/recordings/xxxxxx.mpg file missing. As it turns out, I hadn't bothered to change the default hostname on my remote frontend either, so MythTV got "confused" into thinking the remote frontend was the local machine. I changed the hostname and voila, magically it started streaming the files and my file missing errors went away.
