It's not the issue of files being refreshed, that's not a problem having to navigate in and out of a folder to see the new files.
I think he means the refresh of renders?
I've noticed it too:viewtopic.php?f=6&t=11559
It takes up to a couple of minutes sometimes before PMS sees my TV.
Prior to 1.30.1, PMS saw my TV in a matter of seconds.
But I am using a wired connection to my PS3. Last time I used wifi the files refreshed as well did the connection to the PS3 via PC.
With wired I have to restart PMS if I get the "PS3 has not been found. Is it on? You can also check traces and/or configuration, or also debug.log file". I can leave my PS3 on and it won't connect to the PMS. Unless I restart PMS and it syncs in a matter of 4 seconds.
Also I've noticed that if I have my PS3 on and restart my PC, PMS as a startup windows service
it will not connect. Unless I kill it and reopen it.
I can't remember what version worked the best. But I know it was with the green play button icon, a version or two before the last of the green icon.
