Rick, did you get the logs I emailed you on Wednesday night? I would like to get this working before my evaluation period expires in another 10 days or so.
I did some more testing and the problem seems to be with the transfer of the MC.dic file, as my previous posts hinted.
Using Windows Explorer, I can copy mp3 files directly to the NuVo with no problems. But the NuVo looks different in Explorer than any device I have ever seen. It doesn't show up under "Disk Management" and has no drive letter. Under the "NuVo NV-M3" entry is a "hardisk media" folder (that is the right spelling), with a type of "generic hierarchical", total size 148 GB, free space 147 GB. Under the "hardisk media" folder, there are folders for "Albums", "Music" and "Playlists". I can copy mp3 files to the "Music" folder and sub-folders with no problem.
But when I try to copy MC.dic to the same "Music" folder, it fails with "Cannot copy MC.dic. The device has either stopped responding or has been disconnected." after 3-5 minutes and I have to reboot the NuVo. If I rename MC.dic to MC.dic.mp3 on my PC, then I can copy it easily. But I cannot rename it back to its proper name on the NuVo, it goes through the motions of renaming, but it doesn't rename it (no error). Trying to copy a jpg files give the same error, but doesn't have the 3-5 minute delay and doesn't lockup the NuVo.
When I try to copy an m3u file, I get a message:
the file <name>.m3u may be copied to the device for storage or transport use only. It is not supported for use on the device itself. If possible use a media program that can convert the file before copying it. If you copy the file now, it will be stored on the device, but may not be presented on the device user interface. Do you wish to copy the file to the device anyway?
If I answer "yes, it copies fine. But this sort of message makes me think I am not dealing with the storage device directly and that Microsoft MTP is doing filtering or interfering or rights management? I have a hunch that is what is preventing the MC.dic file from copying. But since MC is supposed to speak the right protocols, why can MC not copy the file either? If this is an issue on the NuVo side, I will be glad to engage them.
