Doug, Yes I have, for sure! My guess is that we're dealing with a combination of certain sample rates and certain versions of the ID3 tag that lock the file up.
If this is the case, this is going to require a lot more testing on my part when I have some time. With the testing I've done to date, I haven't been able to put my finger exactly on the cause of the problem. As I said earlier though, files with both versions of the ID3 tag that I have created, have played just fine on the BN. Dean.
