That's the reason there's been no Blu-Ray release of the series. Someone somewhere at some point erased the files with all the CG models. The live footage was recorded on film so it can be converted to Blu-Ray quality no problem (they even filmed it in widescreen for future proofing). But the CG stuff was only recorded at DVD spec as they thought they could re-render it later on in higher def when technology advances made it cheaper. Now they'd have to redo everything from scratch and the studios don't want to bankroll that.
