Cannot Copy Files To WD Player - Possibly Firmware Related?

I am having some very strange issues with my WD Player since I upgraded the Firmware to 2.08.13.

When I try and copy a file (mpeg 4, AVI, WMV) to the player (both wirelessly & hard wired), the following happens:

It copies almost to the end then I get the following error message:

“The operation can’t be completed because an unexpected error occurred (error code -51).” I am copying from a Mac. i can copy a small file over (like a new folder). I have 160GB of free space.

Then all the content disspears from my drive. it shows 0 files in the Video folder and I get the following message: “There is no media in the content file”.

I have to power cycle the player to get the Video content back.

So now I am unable to copy any new content on to the drive. Any ideas?

Just to update the situation…

I installed the previous firmware version: 2.07.17. This did not fix the issue.

Before the issue occured, I could drag and drop a new folder to the Live Hub via my Mac. When I do so now, the folder shows up in the Live Hub (viewng from my Mac), but does not show up on the Live Hub itself (viewing from TV).

Hope this helps…
