Advanced META Data for files?

Question

I must first disclose that I am anal when it comes to how my iTunes library is sorted and displayed. At least, I thought I was, until I got the Apple TV2. Every song has almost every field entered to provide full information on the album, artist and song... I feel it's necessary when searching using an iOS device to have all this.
Now, as of recently I have began importing my TV DVDs into iTunes so I can rid myself of having to use a DVD player. I Rip the DVDs using Handbrake. Unfortunately the DVDs have basic information and don't supply the full metadata for each individual episode. A lengthy trip to IMDB solves this, but what i am finding lately is that although the preexisting meta editor in iTunes only has limited basic capabilities.
I am finding that with TV and movie files the meta editor isn't video specific, it's still looking for album artist, composer, etc. that is more related to music files even thought the media style is set to TV Show or Movie. A big gripe was that when viewing the Movie on the Apple TV2 it would show the Actor, Director, Writer, and Movie Rating information for movies I had purchased off of the iTunes store but did not give me the option to do so with my imported DVDs.
I have branched out and tried out a few programs that are more devoted to advanced metadata editing such as VideoDrive (ripper and meta editor) and MetaX but have encountered problems with each that i don't like.
I'm curious to see if anyone else out there is as anal with their tagging for their iTunes libraries and have come across a program or programs that can automate the task of editing and can do it accurately.

It seems that others have had the same question as me as there have been many view of this but only ChrisCA's helpful response. 1 year later I am back to share my solution to my own problem so that others in the future don't have to do the year of research.
I still continued to use most of the programs listed in my earlier post for the greater part of the year. It has only been recently that I managed to find a fully suitable program.
Videodrive (FREE - http://www.aroona.net/VideoDrive/Home.html) helped me out for a bit as it integrated very nicely in to iTunes, but if you were doing a batch IDv3 edit, it would only show you the first option and then automatically write the others even with the information being wrong. It was quite good and fast if it found the right info but unfortunately it wasn't very friendly for making adjustments.
I stopped using MetaX (FREE - http://www.kerstetter.net/index.php/projects/software/metax) and MetaZ (FREE - http://www.macupdate.com/app/mac/36029/metaz) shortly after posting this question. The GUI was very primitive and sometimes the search function turned back results that was nowhere close... if it turned back search results at all. It just didn't work the way I hoped and therefore it got the axe.
Which leads me to my final program, one that I have been using for a few months and the one that I recommend to anyone.
iDentify ($9.99 - http://itunes.apple.com/ca/app/identify/id418080764?mt=12) I soon found out that in order to get programs that you want to work, you usually have to pay for them. I found iDentify on the Mac App store and bit the bullet hoping that it would work as promised. I was pleasantly surprised that it actually worked better.
iDentify actually returns similar data as MetaZ and videodrive but with the added benefit of advanced search fields. You can either input the video's title or have it search by the IMDB (http://www.IMDB.com) code. If it doesn't find the right information by itself then you manually load up IMDB.com and copy the IMDB file tag in the address bar (example: http://www.imdb.com/title/tt0365748/ is "Shaun of the Dead") then paste it in to iDentify's field. Pressing 'rescan items' then uses your manually inputted tag (tt0365748) and returns proper information for your video file. iDentify then supplies you with editable fields and multiple artwork from many different sources.
iDentify works quite well with batch processing if you have multiple files that need to be tagged properly. This program isn't fully 100% automated but it's quite close, it does supply you with the info that it finds prior to writing it to the file, which is actually a bit of a good thing, after using Videodrive i found out that sometimes you just need to review the results and give it the ok. Usually if you put in the IMDB tag then it finds it perfectly. I don't think that I have come across any that displayed wrong after manually directing it to the right IMDB web page.
So for those of you who have TV shows or movies in your iTunes library for media streaming then I would highly suggest getting iDentify. This program has been the result of a year long battle with META and IDv3 tagging.
I find that the built in iTunes IDv3 editor is sufficient enough for editing information for audio files so I haven't tested out iDentify with any ripped audio files. If there's request for that, I'll look in to it.
