Is this from comm flagging? I am getting this a lot from my frontend
in regular playback, but there is no discernable glitch in playback
(2xPVR250 and NVidia GeForce 5200). I'll do some testing to see when
it comes. Though if it's coming from a "requiredBuffer" value, is it
possible to auto-increment this value (So each time a rebuffering is
required, the "requiredBuffer" gets 1 added to it). This'd make these
errors go away in very short order (As the system finds a suitable
value for itself). Again, though, this does depend on what's causing
these.
