The "NEW" problem is back.... 
.
........
Here's the issue in a nutshell. The file system on the HDD (I am guessing) used in the HG10 imposes a 2GB file size limit. Apparently, this 2GB limit is not part of the AVCHD spec so it is NOT a problem with the format. This brickwall limit is easy to prove. Set the recording mode to HXP, place the cam on a table, press record, and walk away. After 20 minutes, press the record/stop button, plug in the power adapter and USB cable from your PC. The cam's HDD will be mapped to a logical drive (G:\ on my PC) and you can simply browse the contents of the cam's HDD, which is essentially the same structure as a blu ray disc. The video clips (stored as .mts files) are all located in the "Streams" subdirectory. They are incrementally numbered (e.g., 00000001.mts, 00000002.mts, etc.).
If you started with zero footage on the cam and shot 20 minutes of HXP footage, you will find exactly two .mts files in the Streams subdirectory. If you watch the 20-minute clip prior to connecting the cam to your PC, you will see and hear 20 minutes of seamless video/audio. If you drag and drop the two .mts files and open them in your NLE, you will notice 418 samples of audio (originally sampled in cam @ 48K) missing just prior to the splice point and exactly two dropped frames just after the splice point. Doesn't matter if you shoot 24PFor 60i.
If you transfer the 20-minute footage using the included Guide Menu app, you will have two <datetimestamp>.M2TS files. If you open those files in your NLE, you will see the exact same result.
I also converted the .mts files into a Cineform intermediate .avi file using NEO HDV to see what would happen. Interestingly, after converting two .mts files shot in 24PF (resulting in two Cineform .avi files) and opening those two files in Vegas Pro 8.0b (build 217), the two dropped frames were gone from the second file but the audio was exactly as it was in the first raw .mts and Guide Menu converted .m2ts files.
