a couple of days ago I stumbled across Lee Devlins page for the HPMediavault and it recommended Twonky. I installed it and after much visits to this forum got it to work with my PS3.
However If I set the rescan rate to anything other than zero, twonky never stops scanning. at zero it finishes scanning in about 20 minutes to half an hour. From what I can tell I don't have a huge library, 20 000 audio files, 6000 photos and 200 videos. -1 setting doesn't appear to work either.
