AVCHD Export inconsistent, choppy, white noise

I exported several AVCHD movies from Reveal 8 ( Build 2421(20258).

I am choosing 1920x1080, 30fps from the HD option.

However I am having several problems:
1. The resultant files are not consistently 30fps, some export as 24fps (even though there is no options for 24fps, only 25 or 30fps)
2. The file has no audio when previewed in Windows Media Player although video playback is smooth
3. Some of the files will not import into Adobe Affects Effects CS4 or PremierePro CS4 although they support AVCHD.
3a. When they do import, the playback is jerky and the audio track is just white noise

I have exported the MP4 and H264 in 1920x1080, 30fps without issue but have noticed that the quality of the video (when viewed on WMP) is not as good as AVCHD so would like to see if the AVCHD best option in terms of quality. However, I cannot afford to go Uncompressed or the AVI (x264), files are too massive.

I had upgraded to Reveal X but reverted (clean uninstall, reinstall of 8), jsut did not care for the MagiSpot preivew and other nuances.

System is:
Windows 7 Ultimate 64 bit
4GB, Quad 9450, 2.67
nVidia GeForce GTX 275

ANy help or directions would be appreciated.

Thanks for passing it on. I have pretty much given up on using any HD output from Muvee other than WMV.

I tried exporting in AVCHD, MOV-HD, and MP4 - H264 option from both Muvee 8 and Reveal X to no success.

The AVCHD had the same issue in CS4 (PremierePro and AE) and the MOV-HD, and MP4 - H264 options crashed every time. (I know that AVCHD is not the easiest thing to edit but the fact that it is not playing back properly at all is suspect although FreeMake Video Converter allowed me to convert it to an MP4 when I tested this option).

I tested the export on 2 separate machines, on V8 and X to make sure my hardware was not bad.

What is odd is that in both versions (clean installs for each every time) with all the latest Quicktime versions and Updates, etc., I could not get a good export from anything beyond WMV in the HD export option.

I have log files and can give you all my source material if you want it for testing - let me know and I can provide it to an FTP - but I have moved on and know that WMV is my only choice since I need to generate the videos (kinda sorta) now.
