I am at a total loss. I've been getting choppy video performance since upgrading from the Aprilish release. At first I suspected my NAS, then my LAN performance. Tweeks have improved read speeds back to the 23 mb/s range. I've reinstalled the software, including total uninstall and reinstall with no improvement. I then tested playing a mkv file on the local hard drive and to my surprise the same thing!
I have not tried a m2ts file yet locally.
From the NAS, videos start fine, but after about 30 sec the choppiness starts again with read speeds in the 4-5 mb/s range, not fast enough for HD movies.
Any ideas, as my next move would be to rebuild my computer, but obviously don't want to do that.
