I have an MRSS that works in my browser but not in FuneralScreen.

Due to the fact that the sample MRSS feeds aren’t hosted by us, some of them can behave erratically. As it is, we have no control if the MRSS feed will play or not. Most of the feeds will play,  If you need a reliable feed that is sure to play, you might want to consider a paid feed from Screenfeed.com.
