question about T.V. shows

Fist let me start out by saying I love the software, it takes my i pod touch and i pad to a whole new level of coolness. The question I have is: I have a rather large library of T.V. shows that I have converted using handbrake. I am trying to find a way to tell what episodes are with which seasons. I open my folder and it just lists all the T.V. shows in one area. That would be fine but on the thumbnails instead of showing the image of the season it just shows a pic of the episode. this makes it confusing to keep track of what season I am watching so that I don't get out of order. I would have them separated into individual seasons but i also have the shows in my i-tunes T.V. folder which i-tunes does not allow for separate folders.

So my question is: is there a way to place thumb nails of the actual season poster, or is there a way to separate them for easier selection of each season, or is there anyway to set it up where the T.V. viewing using Air Video is easier to tell which episode goes with which season. I had a last ditch idea to place a 1.2.3. etc. behind each episode title to tell which episodes are from season one, two, and so on. Any help would be greatly appreciated, and if I confused anyone on my question (which has been known to happen) I am willing to try and clarify, and simplify it as well.

Thanks again.

I am running Windows 7, and am running the latest software update for Air Video.

P.S. It is killer for movies. I don't even take up room on my devices anymore with movies unless I am going on a trip or will be away from my wifi for a period of time. Keep up the updates and I will be a loyal customer for years to come. I have even got my brother and his family on board for using it.

Unfortunately right now the thumbnails are always generated from the video itself (rather than a poster). Are the TV shows in a regular folder or in an iTunes playlist?

Well after putting you all through the hassle of reading my question my brother was kind enough to let me know I was making it much harder then I needed to. I simply created a folder for all the shows I have converted and placed them in that folder. That way I can set up sub folders and name them season 1 season 2 etc. Then all I had to do was re associate them in Itunes then all was well. Now they show in Itunes and I can watch them by season on airvid. which is what I do all the time now. I consider myself a somewhat-techie but for some reason that issue was bothering me like crazy.

All is well now and thanks for the reply
