Most likely bad files. Please upload them somewhere and post
links here.

further info:

The MusicMatch V7.2 player reports two new sample
files correctly as VBR.

The Archos software as follows:

MPEG1 Layer 3 VBR, 134 kbit/s 44.1kHz, and
MPEG1 Layer 3 VBR, 107 kbit/s 44.1kHz

RockBox 1.3, 160kbit constant rate.

It is repeatable, going from MusicMatch 7.2 to RockBox
1.3, as far as I can tell.

I will test them on another player to make sure this is
not just a MusicMatch issue when I have time. Not a
serious bug anyway, the files play just fine.

There is absolutely *nothing* we can do until you provide us
with the files.

I repeat: Please upload them somewhere and post links here.

Your files contain a VBRI header, and Rockbox only understands the
Xing VBR header. That explains the 160kbit/s bit rate. We will add VBRI
support as soon as we can. Thank you for reporting this.

I have added partial VBRI support in the file parser, but the time info will still
not be correct. Work is being done on that too.
