I don't know if this will help, but I have a cheap music player that has
no trouble with ogg files encoded at quality level 0. However, I
accidentally encoded some files at quality level 3 (the default) and
found that only half of those played. The others showed a track length
of 00:00.

You seem concerned about a bad Grip configuration setting. What happens
if you encode ogg files from the command prompt instead of using Grip?
