Just out of curiosity, what firmware is on the unit out of the box? I see that the Motorola site has a version 1.01 posted, but a little bird once told me something about a 1.02 release.
The aforementioned little bird doesn't have the release notes anymore for some reason, so I can't say what was supposed to be fixed in 1.02. It does appear that it never was qualified for release, but I'd guess that was due to lack of interest on Motorola/Rio's part rather than any problems with that release. That little bird has been running 1.02 on his player successfully for a year now without problems.
