MACVOYAGER  - Problem 1: If you click the link above you get a page of characters. Solution: Shorten the link one step,

Remove everything after /MacOS/

then right/control-click on the link on the page to mpeg2enc.intel (NOT mpeg2enc, presuming you are on a Macintel) and choose to download to your desktop.

- Problem 2: What you get on your desktop is a file named 'mpeg2enc.intel.txt'. The name the installer requires is specifically 'mpeg2enc'.

So change it. Dump the '.Intel' and dump the '.txt'. (Stupid that they don't clearly tell you this, but remember these are Unix geeks who don't care about making things simple. Another reason to love Apple. They do care).
