Update: its fixed! that what I get for only half reading the guides, I downloaded that elecard mpeg codec thing and now it works.... funny thing is I dont remember having to do that before, but who care. I'll leave the main message here incase someone in the future has this problem.

I had to format my system because of a serious hardware upgrade and after doing so I can no longer open most mpeg files... some of the files in quesiton are from vobs that have been split so that they are the video componet only (no audio) and others are files that I have made WITH TMPGenc! I've even tried formatting again to fix this problem...

For example I took 3 older mpeg files and joined them together just fine using the MPEG Tools earlier, but when I try to load that file into the program it just says that its Unsupported! I have all my software and codecs installed just like last time.

One last note, sometimes the program complains about there not being DVD Player software installed? But of course there is, that problem is not major though as it was happening both before and after the format.

BTW I'm running Win2k. Help!
