Am able to confirm the website seems to be gone for this. I use MacDVDRipper Pro, and MakeMKV for my media management. Both are both actively supported and can be purchased. MakeMKV is essentially free, but without a serial the beta releases expire. So a serial prevents this, and I think it's a great program, especially for ripping Blu-ray discs, so I paid to support the developer.
Does The Little App Factory have an explanation why version 1.6.9 must be downloaded manually? This plus their news page* being full of spam makes me very suspicious.
