No worries chief, glad to of helped!
With regarding to 'fitting more more episodes onto a DVD', currently you may realise from a shop/store brought DVD that you can only fit around only 4/5 eppisodes onto a DVD. This depends on how long the clips/episode are. The shorter the eppisode the more you can fit.
However, if you were recording a series from TV onto a standalone DVD recorder you can (well you can on my machine)set the quality to be lower thus allowing more data to fit onto the DVD when it is burnt.
The other alternative is to just copy over the content (I assume the video clips are divx's) straight onto a DVD. The only downside to this is that you have to check that the DVD player is capable/compatable of playing Divx files.
Most DVD players are compatable with dual layer disks, these are know as DVD9.
Hope that helps!
