Does THX Certified DVDs mean good quality video?

[Dusty Chalk]

So you are saying that THX is just a process, and it doesn’t care if source material (audio&video) is flawed?

That would mute the whole point for THX existence, wouldn’t you say?

Well it's supposed to, but it doesn't (I.E. it fails).

And yes. Albeit, I think you meant "render moot", not "mute".
