Are these 1hr or 30 minute episodes? What format are they in now?
When I capture tv shows, I’m usually working with one hour shows minus commercials, so it works out to about 52 minutes of run time for each show. In dvd video format, I usually put two episodes per dvd disk, but I’m trying to maintain the highest quality possible, and so my encoding uses high bitrates, and quite a lot of room.
To put four episodes on one disk in dvd-video, you would be using marginal quality encodes, and I’m not sure you would be pleased with the results.
It is entirely possible to go to xvid or divx and have each episode at 700mb or so, and retain very good quality. You’d need a dvd player that can play divx avi files though.
You can use Nero Vision to convert your episodes to dvd-video format. It isn’t the best option, but is convenient and you can probably fit them all on one disk, just at poor quality level.
But it would really help to know what format they are in at the moment.
If you don’t know, open them with MediaInfo or Gspot video utility and tell us their specifications.
