i tried it several times with usb hdd plugged in but with autoscan off. ok for both pohd1 and mini1.

copying srt files via usb to hdd at the player did not work with r4824, so no surprise with r3966. you have to copy direct from pc to hdd.

two things i find better with r3966:
. playing flac files now is smoother than r4824.
. i used to have a strange problem with tv going off when i connect via lcpm to avr (old one w/digital coaxial, no hdmi); seems this has been eliminated, good!
guys, if you find it slow to navigate, just turn off auto scan and turn on clear history.

tried all 4 green buttons... either nothing or get an "X". i must have tried everything...
someone asked the same question at acryan forum, no response...

how did you tried to copy srt file from usb with r3966? where is the copy function?

in older versions, you can delete old folder, copy the whole new folder with srt file inside, it'll work.
