Ahh, that makes more sense than 1000 TS packets. I would think that
2MB would work most of the time on a reasonably fast machine as long
as you were only recording one or two HD stream[s]. But it should
probably be resized according to
So that slower machines and more recorders can be handled.
And we really need to report when the packets are dropped so that people
know to increase this setting. Some playback problems look identical to
dropped packets on the recording side do, to the typical user.
