Is there a website that tells which episode of a tv series is on which disc? I used to use rewind @ dvdcompare.net, but it seems to be missing a lot of new series.

Unfortunately, that sort of information isn't written on the box covers, so most of the DVD information websites don't list it.

I've spent years looking for a reliable website that would list this information and never really found anything good. I just started making my own in word documents. But I have realized lately that netflix does a good job of at least telling you what episodes are on what disc (but not necessarily special features)

AllMovie used to for at least a number of titles. I haven't visited much since Macrovision/Rovi purchased them as I didn't care for the site changes. From the little I've used it since, I'm not sure if all that info still remains or if a lot of it got lost in the makeover.

I just looked up a few shows as a test and they didn't seem to have the "releases" section and data they used to for them. I'm not sure if I just picked a few they didn't (though popular ones that were released years ago and should have had that data at one point).

Sadly, the site seems to be a shell of its former self.

The only other thing that comes to mind is to pay for something like DVD Profiler which would have some of that.
