TwonkyMedia Crashing when browsing videos.

[hangfire]

Twonky Media Server 4.4.9 crashes every time I browse the video directory and only the video directory with the PS3 with firmware 2.50. This is not due to my server OS or the router or the wifi server > wired client as it works *PERFECTLY* with the Xbox 360. Details, log files and event viewer entries are as follows. I have also rebuilt the database.

Radio stations: 0
Network type (Wired/Wireless)
Mixed the clients are wired the server is wireless. 802.11g

I have also attached the ini file from the appdata directory, the event log from windows vistas event viewer and the log file from twonkymediaserver.

On possible peculiarity is that I use Twonky to monitor an iPod which is in use as an external HDD and a network drive which is on the network on an XP machine on Wifi. However I discount this as I said before it works flawlessly on the 360. Any help would be most welcome as I am incredibly frustrated with this process and have tried emailing TwonkyVision and have received absolutely no reply as of yet.
