Between those two, I'd personally choose the Sony miniDV camera.
1) You're only limited by the number of tapes and the amount of juice you have.
2) Lots of extra mini-DV tapes are less expensive than lots of extra SDHC cards.
3) 40X optical zoom is really nice for concert shooting, but you might even want to push it a little into the digital zoom range for even better close ups. My experience with my own old gen Sony mini-DV camera is that Sony's digital zoom function is pretty darn nice and doesn't start pixelating until, on my camera, well into the digital zone.
4) Zeiss optics on the Sony should be better than the Samsung...even if another camera has better resolution, if the optics suck the resolution does you no good.
5) The color of the other one makes it look dumb.
My opinions.
