Problems Cutting with VirtualDub

[scribbles]

I'm new to this whole scene so please stay with me. I have a DiVX that is 1.02gb. I need it cut in half so I can burn it. I followed instructions with a couple different sites (including this one). AVIChop just made two 1.02gb files (useless). With VirtualDub I set the Direct Stream Copy (a&v), I marked the beginning of the segment I wanted. Went to Jump To Frame... and chose a random halfway point, the marker on the timeline went to the middle and I can't do anything else with this program. It won't let me click on anything after I do that. Everything I try to do moves super slow so much so as to make me think the programs screwy. I'm dying here. Can anyone help me?!

Hrm, I just noticed that when I load the file into VirtualDub, and go to Next Keyframe it goes right to the end of the movie. If I even touch the timeline it just hangs. I know this shouldn't be, any ideas?

Sounds like you have key frame problems, did you make the AVI ?

In Vdub, select File > Open Video file, But before you select the AVI, check the box that says "Pop up extended open options"

Then select Open on your AVI file, another window will pop up, check the top one that says "Re-Derive Keyframe Flags" and click Open. See if the editing is now improved.

If you click a keyframe and it jumps to the end, it sounds like there are no keyframes, Some Mpeg-4 V3 AVI's are like this.
