AVCHD Rendering Tip
I have found, as many of you have, that there is an inherent problem in rendering from AVCHD 1920×1080-60i to the same format. The audio and video will fall out of sync and there will be a length/time discrepancy which will be noticeably longer when looked at in the Windows environment. This has been acknowledged by Sony. I have been told by their tech support that this will hopefully be fixed in the forthcoming Vegas Pro 9.0d update.
Passing the rendered clip thru a muxing program has been proposed as a solution to this problem. Sony cannot officially condone this as this is using a separate, non-Sony program. Passing the clip thru a program such as TsMuxer does indeed fix the audio/video sync problem and the length/time discrepancy. There, however, exists a new problem where there is a short stutter occurring just prior to transitions. I have found that a single frame will get duplicated approximately three times accounting for this stuttering.
I believe that I have found a way around this problem by doing the following:
1) Render the video stream separately using same resolution as the original. This will generate an AVC file.
2) Render the audio separately.
3) Place both files into TsMuxer to generate/mux a .m2ts file.In the final clip there are no apparent discrepancies with length/time, audio/video sync issues, or stuttering/frame duplication. I hope that this is of some assistance to those encountering the same problems.

Thanks for that tip. I know it takes many hours of trial and error to come up with these workarounds. They really are appreciated. Let’s hope that Sony fixes this soon.
