Typically TV shows are viewed by Series-->Season-->Episode.
When in disc form, it's easiest to assign multiple episodes to each disc.
An example of tag fields you could use for a season of Frasier:
1st disc
Series:Frasier, Season:01, Episode:01-05
2nd disc
Series:Frasier, Season:01, Episode:06-10
3rd disc
Series:Frasier, Season:01, Episode:11-15
There are a few ways to get the values into the fields: Manually, tag on import, fill properties, carnac, etc.
If you want to use scrapers to get info for each episode, you can use particles first.
