It is simply not true! YUV422 is lossy by nature because the chroma components are subsampled.
However it can be considered lossless in case your source is a native YUV422 data, which is true in most cases. But still calling it lossless in general is false.
You can expect an average compression rate of ~4:1 (lossy) compared to YUV444 (or RGB24) and ~3:1 (lossless) vs YUV422.
In practice it works quite well when it doesn't crash... Unfortunately that happens often randomly.
This might sound stupid but I downloaded and installed by right clicking on the huffyuv.inf file and select "Install now what, where is the program, I dont see a icon or install folder any place, how do I uninstall?
Thanks in advance

I only partially agree. Huffyuv 2.2.0 seems to have a problem with RGB-encoded files. It indeed manages to crash every application (e.g. Virtualdub, Premiere, Media Player Classic) that try to playback files that were encoded with the RGB compression method.
