Yum Hi again - I was able to find some sample files that are shorter and I should be able to send them. From what I can tell, this problem seems to happen with the lossless audio codecs - Dolby TrueHD, and now I also discover the problem with DTS-HD audio as well. I will send the files to the e-mail address listed above.
Compressed audio like AC3 and Dolby Digital Plus do not seem to have this problem. Thanks.
