FS#9299 - BBC dowload ID3v2.3 tags not read reliably
I am quite prepared to believe that this is fundamentally a BBC problem.
Amarock can extract; title, artist, album, genre, year, and a very long comment from “Material World” downloads. Rockbox r18310-080818 can only extract the ID3 version (2.3) and the first three letters of the album name (Mat).
mp3info claims that there are no version 1.x tags in the offending files.

This is most likely caused by the long comment tag. For some reason, Rockbox still doesn’t read more than 300 bytes from the ID3 tag, despite the Metadata-On-Buffer system.
When you say “can only extract” do you mean the database, the ID3 info screen for the file, or in the WPS?
I’ve seen this as well (also with BBC mp3s). It is “solved” by removing the APIC tags
I was only looking at the WPS. It looked a bit suspect, so I created a custom WPS that just displays the ID3 tags described in the manual.
$ cat Test.wps
%wd
I didn’t think to look at the file properties screen. (I didn’t realize that ID3 data was there.) Path, Name, Size, Date, and Time look good. Artist and Title are blank. And Album has only the first three letters.
The database has entries for “Mat” and “Mate”. I assume different truncations of “Materials World”.
This file (http://downloads.bbc.co.uk/podcasts/radio4/material/material_20080814-1800.mp3) also includes a rather large (53544 bytes) APIC frame (”album art”).
I’d bet that removing the APIC frame made no difference at such. Re-ordering the frames is a more likely explanation (so perhaps you got album and artist but not title). A small edit of any field is likely to have the same effect.
Increasing the ID3v2 buffer could help, yes (in the linked file, the comment alone is almost 600 bytes). Why not do it for SWCODEC targets at least?
