For some reason I'll watch only one episode of some TV show. Later (months, a year, sometimes more) I'll decide to try that series again. It's the same episode.

And not only the current season (where there's a 1 in 20-25 chance, i.e. see a new episode and then catch the summer repeat) but also where they show the entire series like how SciFi does Stargate Mondays. (They still do that right?)

It's more annoying than neat. Here I want to get a feel for a show and I see the same episode twice.
