One idea that I had is that the updates to Premiere Pro
4.0 have slowed the program to the point that Intel 4500 MHD Graphics Chip can no longer keep up with HD mts files.
Does this sound reasonable?
Thanks. I followed the excellent instructions on the benchmarks and sent him a file

I think that the speed of the graphics chip is limiting playback of HD files. Does this benchmark test this?, Comment
This shows a couple of limitations:
1. Only a dual core CPU
2. Only a single disk
3. Integrated graphics card.
The three factors combined lead to rather low scores. 48s for the AVI test show a severely lacking disk setup. The render timeline results show both the lacking disk setup and the graphics card limitations. I'll wait for Bill to include the results and to give further comments, but you have a seriously underpowered system for HD material, specially if it is AVCHD.
Thanks again! Yes I am trying to work with AVCHD, which puts an additional burden on the processor. Unfortunately, I am working on the road and thus am limited to a notebook. I could attach a 7200 rpm USB drive that I have as additional storage, but I do not think this would address the video preview problem, which is my main issue now.
Your notebook is certainly not bad. It is in the same league as my own notebook (Vaio VGN-FW31ZJ) but is no comparison to a dedicated desktop/workstation system. If possible, I would at least add an external eSATA disk for on-the-road use, not a USB external. The main problem is that realistically AVCHD requires an i7 processor and that means a new notebook. Also your integrated graphics card does not help. But it is a rather drastic step to say, get a new notebook. For applications like On-Location it is quite sufficient, for editing you can see the results in the benchmark. 6-10 x slower than the top-performing system.
I strongly second Harm's comment on eSATA for any external. Besides the horribly slow throughput of USB, many (myself included) have had issues with Delayed Write failures and other Read/Write errors.
BTW - if you do envision getting a new laptop, check out the Sager line, before you spring for one.
