Sabatical, Thanks for the reply. I did something like that with Pixela's VideoBrowser and I also compared the final size to the combined file created using TSMuxer. The size of the two AVCHD clips I used were 146,656kb and 995,154kb (sum=1,141,810). The resulting file size was 1,113,133 kb from TSMuxer and 1,137,618 from Pixela's VideoBrowser. They're both close so maybe the Video Browser isn't re-encoding (a good sign).
