Yep. Not only that, but a lot of times they'll discard your lossless codec suggestions as "pfffsssssh! 3rd Party codecs!? We're professionals here, we don't need 3rd party suggestions."

FFV1 also works due to ffdshow. For Mac users, FFV1 is supported by Perian (as of v1.2.2, from April 13, 2011). There's also several other lossless (and lossy, for that matter) formats Perian can potentially support, but they haven't been exposed to the end user for various reasons like stability.

For instance, if I could manage to successfully compile Perian from source, Lagarith might also be an option - at least hypothetically*; I don't know if there were more things to adjust to make it work than what I did change, and since it failed to build in general it's not like I was able to test it.

*Not that the underlying decoder is iffy on it, just the 'expose it to the end user' part. The version of ffmpeg that ships with Perian is capable of decoding Lagarith, with some caveats (namely, it only supports YV12).

Yeah I also totally agree.
The Birds are using humanity in order to throw something terrifying at this green pig. And then what happens to us all later, that’s simply not important to them…

Maybe I'm at a loss too as to what codecs are as well. Could someone give me a brief explanation??

Codec = COmpressor/DECompressor

Video can be represented as a sequence of red, green and blue values (there's other ways besides RGB, but this gets my point across just fine.) If you just leave the data like that (uncompressed), a single episode would take roughly 33.4GB of space (720x480*** pixels x 3 bytes per pixel x 24 frames per second x 60 seconds/minute x 24 minutes).

Codecs compress that information down to a more manageable size by using different techniques, and then decompress the data when you try to watch the video.

This is a gross simplification, but...
Lossy codecs throw away some parts of the video information to make files smaller.
Lossless codecs preserve 100% of the information, and have zero quality loss, but make larger files than their lossy counterparts.

***I don't care about the active region here, the point is uncompressed = big
