I would like to bump this again. I still haven't been able to play avchd files, using VLC which should work, I get about 1 sec of fluid playback and then a lot of stuttering. Any advice for checking out avchd without transcoding first? I tried surfing the net for a solution but the only thing I come up with is people suggesting either VLC or Toast Player (which I both have) to play the files, but neither work (this is on a uMBP late 2008, 2gb ram, 2.4ghz core2duo etc)
One more thing, log says: main warning: late picture skipped (53868 > -2745). I have a FEELING (not sure though, since disk checks says all is ok) that my hdd is performing badly after I dropped my MBP. Could this be the case? Or could any other software slow it down? I might do a clean install of OsX just to check but I would like to know if that could be the reason.
