Orb and MPEG2 Codec(s)

[xmind2006]

Just thought I'd post a question over here since there are quite a few Orb users on here.

For some reason XP doesn't seem to see that I have any MPEG2 decoders installed. Niether Orb, XP's video decoder checkup utility, nor Sherlock 2.0 sees that any MPEG2 codecs are installed.

The problem is that I've installed every MPEG2 codec I could get my hands on and have restarted multiple times, but nothing ever changes.

I had Orb installed a couple months ago and had a 1/2 dozen codecs installed, but have recently reformatted my PC about a month ago; hence why I'm perplexed why a very similar setup doesn't work.

Does anyone have a clue as to what may be happening?
