Now I feel bad for being so mean
Lossy = it drops information, say it removes certain types of color information that your eyes won't notice. Things like MPEG, reg MJPEG,MPEG2, DivX.
Lossless = no information is dropped. Things like Zip compression, programs you download off the infternet CANNOT have information missing from them, so you have to compress them, but preserve the data so that when you decompress it, it's a exact copy of the original.
HuffYUV uses that type of compression. So there is NO data loss to the original image.
Now if you have MPEG2 .vob files, those are lossy and have already had a lot of data thrown out of them(data you probably won't notice is missing when you view it). How digital video conversion works is that it takes that compressed data, uses the codec to decompress it into a uncompressed bitmap frame, then takes that uncompressed bitmap and then sends it to another codec so that it can be compressed again.
So going from mpeg2 to huffyuv will not save you space, since it will be compressing, what your mpeg2 codec has already decompressed.
It's basically acts like it was never compressed at all once it comes out of the codec.
Now lossless MJPEG is alot like regular MJPEG except it doesn't drop any/as much video data as regular MJPEG.
You can pick up a lossless mjpeg codec <a href="http://www.jpg.com/video/">here</a>. Tho you have to pay for it.
