Default Lots of stuttering and audio distortion on Sony Vaio Notebook

I am having a lot of problems with AVCHD files , just not playable . Is this a hardware or a config problem. I am using a I5 laptop with 8gb ram. All advice highly appreciated, thanks.

What version of the software are you using. You can convert the files if needed.

Also, what type and speed is the drive containing the AVCHD clip? If this is a standard mechanical 5400rpm drive, this could be the problem.
Even though AVCHD is driven by CPU, if the throughput on the drive is very slow, as on a 5400rpm drive or slower, it will drag the playback down.
Convert the clip to HQ and give a try on the same timeline. Compare the two playbacks.

AVCHD is highly compressed and normally wouldn't require more than 24Mbps of bandwidth, which is essentially the same as DV. Even a low-end mechanical drive should be able to keep up with it unless the sequence has multiple tracks.

I'd be curious what the rest of the hardware specs are, and what the CPU utilization in Task Manager is. Also, which Power Profile is the laptop running with?

The clips are already on the HDD.

Cpu usage is peaking at 92% . Power profile is Balanced, Stamina Mode

I agree, a 5400RPM drive should be able to play back a few layers of AVCHD with no problems, what's more important is the rest of the system specs. Just saying i5 CPU doesn't say much as they did a range of i5 mobile CPU's across 3 generations so far and some of them were very underpowered. Having the actual CPU number would help.
If you hold down the Windows key on your keyboard (normally bottom left) and tap the 'pause/break' key (normally top right) it should bring up your system properties. On there it should tell you your Processor details.

Try switching to the Performance profile and turn off Stamina Mode.

I switched to Speed Mode on my Sony Vaio and things have improved a lot, in fact, I can now work on the system . Thanks for guiding me in the right direction.
