So for the longest time PMS has been running great on the default settings. I play 720p/1080p MKV files on a Mac with a 3.4 GHz i5 with 16GB 1600 MHz DDR3 RAM on a wired (CAT6) connection through an Arris DG860 router (thanks, Time Warner!). I've never really had a problem at all.
Sometime last week it all changed though. Now I can't play a video for more than a few minutes without it getting choppy and unwatchable (until I pause it for a few minutes to let it buffer and then I can play for a few more minutes before it happens again). I checked the support guides and made sure I had the latest Java (Version 7 Update 40) installed and the DivX codex. My transcoding is set to all 4 cores. I tried bringing the I even brought the max bandwidth down from the original 110 MB/s to 10 MB/s and I still have problems.
Any suggestions on what might be causing this or anything I can do help determine the cause?
