Hi Neal,
Sorry to hear about your BDP-1 problems. The BDP-1 has a tough time with AIFF and M4A files, so they generally take 3 to 4 times longer then flac files to load into the database. However there are two things you may try to decrease the time it takes for your BDP-1 to load your drive.
The first is to turn off the BDP-1 before unplugging the drive. When this occurs the BDP-1 should preserve the existing library. Then disconnect the drive from the BDP-1, update the drive with your new music. Plug the drive back into the BDP-1. Finally turn the BDP-1 back on, once the BDP-1 boots back up, it will still say updating, but the old library will be made available and any new additions should show up within 10 minutes (if not much less).
The second way you could go about this is to connect to the BDP-1 over your home network. The BDP-1's firmware is designed to share any USB drive that is connected to it during startup, over the network. BY doing this you can add files to the BDP-1 without the need of ever disconnecting the drive from the BDP-1. Once you have copied the files over. Open a web browser, go to the bdp-1's home page, click settings, (default user name and password are both "bryston" without quotes), click Drive Information and finally update database. Within a few minutes your new audio files should show up.
I'll try to find some time to upload a video of how to perform the second method tomorrow.
Cheers,
Chris
