I own the same TV, however, I have not used it under Linux yet. I've been playing a lot of 1080i content from my PC using Windows Media Player 10, and I have not noticed the problem you're describing here. I do, at times, see my video and audio stutter, but I believe it's due to CPU and/or HDD I/O -- most likely HDD I/O. The stutter is very occasional and only lasts for a split second. The PC I'm using is slower than yours, also. It's a 2.4GHz P4 w/1GB and an nVidia 5700 Ultra.
Being that it's only affecting a small portion of your video, I have a feeling your problem may be due to deinterlacing. Perhaps you can try disabling the deinterlacing option to see if it remedies the problem.

Based on the information I read here:

I don't think a dual-link cable would do you any good, as the monitor can display a maximum resolution of 1920x1080. I'm sure that using a dual-link cable shouldn't hurt, but I don't think you'll get any benefit from it.
