You need an authoring program.
There are many of these ranging from free, almost free, budget, midpriced to seriously overpriced.Such as imtoo dvd creator is not free but very useful.
With 200+ shows, what is the average running time of each one?
And DVD-R will almost certainly be more player friendly than DVD+R discs.
Depending on the complexity you need, if making episodic discs I would recommend DVD-Lab Pro 2. It's got a steep-ish learning curve but is cheap for what it does at $250. You would also need an MPEG-2 encoder and a Dolby Digital encoder as well.
Another choice is Adobe's EncoreDVD 2 - this has all the encoding tools built right in, just import the AVI files and off you go.
There are trial versions of both available.
