MPEG 1/2 (MPGV) Codec? MPG movie won't play in QT

I have been given several video to encode, however, I cannot view these source videos in QT or in MPEG Streamclip. In QT the screen is black with no audio and in MPEG Streamclip the screen is white with no audio. This makes me think that I am missing a codec. I can open the videos in VLC and when I look under "Media Information" it tells me that the codec is MPEG 1/2 (MPGV). I have searched online and haven't found anything. I have the MPEG 2 component, I have Perian installed (it's installed twice, not sure if that is a problem), I have all the ProRes codecs plus many more. I am a video editor, so I have a lot of different codecs on my machine. Could the combination of different codecs be an issue? I tried opening the videos on a different machine (which has the mpeg2 component as well) and it didn't work. Can anyone help with this issue? I'm going crazy over here!

G5, Mac OS X (10.6.6), QT v10

Do you have any idea as to why no audio or video came through when I didn't check any transcoding boxes and simply encapsulated as .mov ? Why did I get 12 seconds of black with no audio? (my test clip is 12 seconds long).

Sorry, not really. For me, MPEG-4/H.264/AAC files are more of a "hands on" thing. Between proprietary codecs, encoders with hybrid profile/level features, and/or incompatible AAC data/sample rate problems, these files can sometimes quickly turn into the proverbial "can of worms"—especially if created on a non-Mac platform and/or by a third-party application.

I have FINALLY found the solution. Using VLC media player, follow the above instructions for video, but make sure you only transcode the audio:

This allowed me to open the files in MPEG Streamclip with audio and video. The files I had were from a DTE Firestore device, and I learned that an upgrade within Itunes to iTunes 10.5 wiped out the particular codec, and there was no support in site. I pretty much had a 10 minute offline section in my FCP timeline from footage that was in this codec, but now that I am able to open in MPEG Streamclip, hopefully the problem is solved.
