Apple TV crashes iTunes

Hi,

I using Apple Tv (black) to access my iTunes (10.3.1(55)) which is on my MacBook pro running SnowLeapard 10.6.8.

I can use Itunes on the Macbook OK

I have a few sporadic issues when I access via homesharing "computers" from AppleTV (4.2.2 (2203)) - latest update today:

example 1- I play some music, OK, I then select a movie - Ok... I then go to select another movie and it says something to the effect of "loading my movies". The spinning progress "thing" on the AppleTV never stops, I left it for half an hour, no actual progress. When I go to my Macbook the spinnig color wheel is going for iTunes and I have to Force Quit... send issue to apple etc.

example 2 - I tried accessing iTunes on another Macbook (10.6.8), same thing... straight up it says trying to load library and it hangs iTunes on that Macbook, which eventually needs to be force quite.

Any ideas?

regards

Adam
