Mpeg-4 Problem (Codec?)

[Ignis]

I have some movie files and they seem to be Mpeg-4, they say "Mpeg-4 Movie" under type. But I can't seem to find what plays them. I have QuickTime, and it says "Error -50: An unknown error occured" if I try to open them. Windows media player can download the audio codec but not the video codec. Opening them up with AVIcodec does nothing, the program shows no codec for them. I feel like I'm missing something really obvious, but I've tried a couple of Mpeg-4 codecs and nothing makes a difference. Any ideas? Thanks for reading.

what does gspot say?

try ffdshow or play with vlc media player.

[Ignis]

GSpot is only for .avi, these are mpegs. I already tried ffdshow. But vlc media player works, but that's not too convenient to have to open everything with it. Any idea how to get it to work with Windows Media Player?

Gspot works just fine with MPEGs. You must be using an old version. 2.52 is the latest. If VLC plays it, but not MPC, then you are likely missing the needed codec.

It might work with mpg's, but best I can remember it doesn't support mp4's. Try Media Info.

Video Inspector, maybe?

I'm unclear about Gspot and MPEG-4s also. But I don't have any to test it on.

I did see this from the Gspot changelog, latest version:

15 Sept 2004 040915
Reworked parts of the MPEG-4 parsing routine. It was failing to even identify some files as MPEG-4 altogether, and when it did it sometimes provided erroneous information (the BVOP indicator in particular).

You get the B-VOP indicator, etc. when you open an XviD, DivX, MPEG-4 avi though so it could just be refering to that.
