I recently bought a PlayonHD!2 and I'm experiencing a problem with the Torrenting option.
There are 2 main errors which occur every 2-5 minutes, and I have to manually pause/restart the torrents every time.

Normal State: http://screensnapr.com/e/OB3JhB.png

[*]Here's a picture of the" no such file or directory"error.

Can someone help me out ?

Yep, I have exactly the same problems here and no solution yet.

I found this post from 2009 where someone experimented with transmission and ran into the same problems as we do, but I cannot find a solution there.

Thank you , I've read through the thread and came to the simple conclusion the files are just corrupted, as newly added torrents do not share the same problems.
As for the one's with errors I deleted them, and simply restarted.

One last question, should I set the download folder as Default ( /tmp/hdd/volumes/HDD1/transmissionDownload)
or should I change it to /tmp/hdd/volumes/HDD1/movie ( As those are the catogory folder(s) ).
I remember the old BT Client would move it himself if I'm right.

Got the same problem. What drive do you have? I've got a WD Caviar Green 2 TB wd20ears. It also plays up when you try to copy the files. I've got a feeling it's to do with the drive. I had problems with my qnap and lag issues until an update where they supported the WD Green drives. Now I have no problems.

Firmware_PV76120_v8.5.x.r3966
WD Caviar Green 2 TB wd20ears

I've no Idea never took the drive out of the bay ( Came with an Drive when I bought it ).
To be honest i'm quite disappointed and it's just sitting there in the box catching dust while I use my WD Tv Live hub. Whenever new firmware gets released I might try it again but for now I'm done with AC Ryan.

Waiting for the staffs to comment
