I don't often do this, but this past weekend I tried to do so for two 
different recordings and was surprised at how poorly it performed. This 
used to "just work".

It would take at least 60 seconds to start playback and, once it did 
play, jumping forward would sometimes cause playback to halt for 2-3 
minutes. Several times MFE bus errored. In my case, it did not matter 
how close to the end of the recording was being played back; I was at 
least 45 minutes back from "live" when the troubles began. These are 
some of the many log messages:

I don't necessarily think the ticket pointed to by the OP is relevant, 
due to the fact that it happened far back from "live". In my case, the 
recording device was a PVR-350, in case that matters.
