Silly newbie questions, but I just want to play it safe:

Is mkv2vob v2.2.4 completely safe to use and spyware free? Does it call home or try to connect to the internet?

Is the mirror link to download form videohelp the best/safest place to get it from?

Same questions with tsMuxeR... safe and spyware free? Get it from here? Call home?

Better to use 1.8.8b or 1.8.4b? The official website lists 1.8.4b as the newest version to download:

Where did 1.8.8b come from? Totally safe, etc.?

Thanks for the help and humoring me...
