All a matter of opinion/personal taste and a number of other factors,
I suppose, such as quality of input source, output resolution, etc.
For my money, capturing 1080i at 6 mbit/s is verging on unwatchable.
13.5 Mbit/s, however, is really really fantastic and only shows a
slight bit of "softening" compared to the initial source. I say if
people want to capture at 6 Mbit with mid-spec systems and are happy
doing so, as long as they have the understanding that they will
probably have major headaches if they try to scale up to the max, then
go for it. It's somewhat important to note that the OP was nearly
maxing out a core *before* audio decode and sync on a 6 Mbit/s
capture. Assuming processor usage was linear as bitrate increased
(which, of course, it isn't, but close enough) and adding audio
decode/sync into the mess, it's more a support of my assertion that a
higher power CPU is needed than a refutation of it.
