How long are those episodes? 24/30 minutes, an hour, two hours?
You see, single-layered DVD have limitation. You just cannot throw 8 episodes on it and call it a day. They work like a CD-Audio except it's video. Also, like the VHS, the DVD has multiple settings. In 1 hour mode, the quality is high, 2 hours and the quality is normal and 4 hours and the quality is meh. This is why I asked you how long were your videos.
Anyway, you can try DVDFlick : DVD Flick
It can create menus and convert your file automatically for you, etc. Also, if they are movies and want to make DVD-Videos, forget it. You CAN'T put 4 of them. Not even 3. 2 of them MAX. I know that the DVDs are expensive on your side of the world but if still really want to put as much data on a single disks as possible, you better burn your file on Data DVD or aim for dual-layered DVDs (8.5GB).
Hope that helps.
