AVCHD requires a lot of muscle. Maybe your PC does not have enough muscle. Enough would be something like i7 overclocked with lots of RAM and good disk I/O.

I do have a 3GHZ quad core 8Gigs of memory. Windows 7 64bit. It plays back flawlessly in Sony media browser. Anyway thanks for the input. Wow an i7 maybe!!
Though AVCHD does take a lot of resources, especially the CPU, yours should be OK. Now, with non-AVCHD material, the I/O sub-system, i.e. your HDD's come heavily into play. With AVCHD, it's more CPU intensive. Still, tell us about your I/O, as there might be a bottleneck there. Just a shot in the dark.
Why don't you run the PPBM benchmark test to see how your system performs: http://ppbm4.com
If you send the results to Bill he can incorporate your results in the overview and it will show you how your system compares to others.
I have a Tera byte on board and another tera byte connected through an esta. I run projects on my none system drive. also have nvidia 8800 with 8 M on board.
Thanks Harm, I'll give it a try, by the way I'm looking a your eariler post on 4 ways to improve your PC performance......wow thats a lot of info to digest. I am looking forward in reviewing.
Yeah, there are a number of posts in the hardware forum intended to help editors to get the most from their system, but as time progresses and new articles are added, they are no longer all shown in the same spot. I still hope that even though some articles may appear outdated now, they still hold valuable information. With over 50K reads it appears others found it useful. I hope you can profit as well.
BTW, Bill has already announced that his PPBM page will be updated shortly so I do not think it is a great mystery anymore, but I have tried to help Bill with the presentation of his results page and this is what it will look like, while giving you some feeling for your results at the same time:
