I've had the same problem twice. The first was this winter, when suddenly playback of anything (movies transcoded or not, music, photos) stopped playing at about 10 minutes of the beginning. Network errors, DLNA errors, etc. After failing in isolating the problem, I did everything I could, tried several versions of the PMS, reconfigured the PS3, reinstalled software in my computer, checked network...suddenly everything started working again and I didn't know exactly what I did to solve it.
Until yesterday. It is happening again and I don't know what's going on. I've done nothing with the computer and I've tried two versions of PMS: 1.10.51 and 1.11.356. Playback just hangs and no messages in the debug.log file.
Suggestions welcome...I can give more details if someone thinks that can help.
Thanks in advance
