Other tag parsing? Options

[Tinis]

I'm trying to parse other tags, other than those used in %1-%7, such as the Discnumber tag. This at all possible?

Either I'm going blind or it doesn't seem to be in the documentation. Tried searching, too, but couldn't see anything that fit the bill really.

Also, %4 (for album) seems to struggle with full stops, or something? For instance, my preset is set to:
//describe $active np: %name [%4] [%pm:%ps/%min:%sec] [%br %?VBR='yes'<VBR|CBR>/$uc(%ext)]

Which, for the following album, is coming out as:
* Tinis np: Bob Dylan - Tomorrow Is A Long Time [Bob Dylan's Greatest Hits Vol.] [01:05/03:01] [217 VBR/MP3]

Whereas, the album part should be "Bob Dylan's Greatest Hits Vol. II". The tag's definitely not using unicode or anything, I re-wrote them just to make sure. Not quite sure what's happening.

Any ideas on either of these would be much appreciated. Ta.
