with the last beta of h13, i got this error message :
"xxx.mp3 contains ID3v2.2 tags which is obsolete and not supported."
i have to tell you that helium 2009 does not have this error and support well this tag.
have a good day.
This is not a bug, it works just like designed.
Helium 2009 was released almost ten years ago when this version of ID3 was not obsolete.
Since a coule of years back, id3.org, the home of the ID3v2 tag marked this version as obsolete and newer versions of Helium does not support it.
Edit: The new thing about this is that Helium 13.2 gives an early warning message about it.
