On the off-topic matter: jump to the "All I need is a second lossless audio file system" fragment in APE files problem - #5 by Zerow
That list of mine there is a little outdated but the principle for using TTA is right there. [Although recently I have been thinking of switching from TTA to M4A, but it all comes to finding an optimal third lossless audio format, which I would be able to use without serious constrains in Mp3tg, Winamp and file converters. TTA was not optimal but it had the least drawbacks. A right now I am using also FLACs, WVs and of course MP3s]
[As for the reported issue- I will get back to it later on]
