Hi folks,

(I recently bought a cheap portable MP3 player and (of course) stumbled over the same 
problem as Chad Conrad. I then remembered that my DVD player can play MP3s too, so I 
checked: same effect. The portable is a cheap "no name" device; the DVD is a Cyberhome 
AD-M212 if anyone wants to know.)

I think I can confirm the latest news on this: the problem only seems to show with 
stereo encoded files with "short blocks". This _includes_ joint stereo files, since 
these can IIRC switch to normal stereo frames to avoid jstereo artifacts. So using -m 
j lowers the amount of glitches, but IMHO it does not disable them. But: when I either 
disable normal stereo frames (e.g. by using -m f) or short blocks, the glitches 
vanish. Other options I tried (without any effect whatsoever) were:

--strictly-enforce-iso
--nores
-B 224k

so it seems the problem is not bitrate and/or bit reservoir dependant.

I am not around the next week, but if you need an additional tester afterwards, I will 
gladly help. I am no good at debugging LAME, however, since I am only mediocre at C 
and my MP3 technical knowlege ist quite limited.

Regards,
Robert
