Yup... same here. Is this not just a bit crazy?
So, let's just get a bit of a straight line on this. You import a standard itunes compatible file, (i know this as i have been using visualhub now for 3 years to import all my movies and TV shows) and it goes in to the movies section by default. You choose the drop down in Itunes 'get info', TV Show, and name the show etc. Batch or single file, it makes no difference. Then as if by magic, it all pops out of Movies and in to TV shows. Great. All is good and as it should be.
Then you start Front Row and it has a totally different idea of what your media is. I am a little uncertain if FR has started reading the info from somewhere that is not the Itunes library. But i have had some luck with pulling the files out of Itunes and metaz-ing them and putting them back in. however, it is not 100 percent effective.
I can only really see two causes to this. Either my itunes is a bit knackered and it is changing it's database and not the file metadata, thus causing the discrepancy, or Front Row is not reading the metadata correctly. oh.. actually, maybe

has gone a different route of where FR gets the info. But that would mean it had been released without basic testing... unlikely.
I have tried all of the methods listed here and in other forums, and so far only changing the metadata with metaz or x (metaz has a more up to date library) has really had some success.
I have experienced the 'various' and 'untitled' naming of my perfectly named files, as per mentioned above.
It is all a bit touch and go really. To be brutally honest, after spending today trying to report it to Apple and finding out that they do not have a support page for FR, nor do they want emails about itunes if it is not about the itunes store; i feel a little bit Microsofted about the whole problem.
It really is not usual for Apple to make me feel a bit let down. I even searched for a FR alternative today... but there is not really anything as good.
I am hoping to ignore it for a couple of weeks and just keep clicking 'check for updates' :-D
P.S. as an additional bit of info... my APPLETV has no problem with the library. It sees all the files as perfectly as itunes sees them.
