I got my TV back..!
Bought a splitter for my cable yesterday, so I could get a signal into my TV again, and utilize the tuner in it.
That made all the difference, now im actually no longer annoyed by the DP-558. I have a range of stuff scheduled - wee!
I tried to FTP an xvid encoded avi to it yesterday, but it froze up when i attempted to play it, which pretty much sucks. I will have to experiment further with that when I get some more time.
