> Question, do you think the above system config is underpowered to smoothly edit m2ts files?
Yes, definitely. The Sony web site recommends a minimum of 2.8Ghz for editing HD. Also, if you really have a Pentium Dual Core and not the newer Core 2 Duo this is even worse because the older Dual Core technology performs poorly.
> The issue I am having is that playing HDV video playback (Sony *m2ts files recorded at full HD with an SR12) is incredibly rough.
Just so people don’t get confused when they read this, HDV is a 1440×1080 tape based format using miniDV tapes and MPEG-2 compression that plays very smoothly in Vegas on modern PC’s. Your SR12 shoots 1920×1080 AVCHD which is a tapeless format using AVC compression that even the most powerful PC’s today have some trouble with.
