I seem to be having the same issue. I updates to see what TMS5 was like and it started to play up so I thought no problem Ill downgrade but all I get is invalid Image every time. Ive tried restarting the ReadyNAS and tried several different versions of TMS4.4.x all getting invalid image. Ive tried removing the Twonkyvision tab in the streaming page but as soon as I go back there its back again. The new Twonky just wont stop. Oh the main Issue I had with 5 was It was reporting I have 121000 pictures which is about 10x the real amount and the same for all the movies and music and when I browse to it from my ps3 its shows loads of the same folder.
