Yes, you can access files from any drive connected to the Dune Player. This must be done over a network connection. The Dune Player's do NOT have a host USB port. So you can NOT connect a Dune Player directly to your PC using a USB cable. The USB ports are only for connecting external drives and a wifi adapter.
I have several drives connected to my Dune Player setup as network shares on my PC. You can access all the drives attached (both internal and external). I can read, write, and delete anything from the mapped share. You can also access all the drives by login into the anonymous FTP built into the Dune Player.
While testing all the network capabilities I discovered something very interesting. If a data disk (CD-R or DVD-R) is present in the optical drive on the Prime 3.0 you can access that as well over the network! You can even set it up as a network share on your PC! However, if an Audio CD, DVD Movie, or Blu-ray Movie is in the optical drive the share disappears (also disappears in the FTP as well).
This does show however, that access to the internal Blu-ray drive in the Prime 3.0 is possible over a network but, again only if a data disk (not a commercial disk) is in the optical drive. From the opposite end, if you have a Blu-ray drive in your PC you can share that and then access it from the Dune Player's home page. Any disk type will be recognized, even commercial copy protected disks. This enables someone with a Base 3.0 to instantly watch a movie without having to copy it to a hard drive first.Correction: Commercial CD's and DVD's can be played (streamed) from a networked optical drive in a PC without AnyDVD. Commercial Blu-ray disks can also be played (streamed) from a networked optical drive in a PC but, AnyDVD must be running. You can then browse the Blu-ray disk from the Dune Player and select the M2TS file and play it but, you can not access the main menu of the Blu-ray movie. This applies to the 3.0 models.
Keep in mind, the fastest way (by far) to transfer files to a drive connected to the Dune Player is to pull it out or disconnect it and plug it directly into your PC. I personally prefer to store my collections on a NAS or my PC and then stream everything over the network to the Dune Player.mlknez
Dune Players do not support SACD disks. Most DVD-A disks will and should play fine however. The file types vary on DVD-A disks, so I can not guarantee that they are all supported. There can be a combination of DTS and PCM tracks to choose from in both stereo and surround at various sample rates depending on the release. Since we have already affirmed the Dune Player will support just about any audio file type, I would conclude that most DVD-A disks should be supported. Please note though that HDI does not officially list DVD-A disk support.
I am still performing more tests and will report my findings soon. Thank you everyone for your intriguing and insightful questions.
