rmeditor unsupported codec, how to cut rmvb ?

[kclgad]

Hi, I want to cut out part from a rmvb,

I can use rmeditor to do that for some rmvb files,

but for some other rmvb files, rmeditor return
"Error: The input file contains an unsupported codec. This file can not be edited."
example unsupported codec get from media player classic:
Audio: AAC 44100Hz stereo
Video: RealVideo 4 704x396 25.00fps 776Kbps

(1) Can I fix the problem by install new codec ?

(2) I get the rmeditor long time ago, I don't know its version because it don't show it. Is there some new version of rmeditor can do the job ?

(3) Is there any other simple software can do the job ? I don't want re-encode, convert-format, etc.

Thanks for help in advance.

Sometimes, when your file is damaged, it will be difficult to edit. - you often have to cut out the bad segements then append them. I suspect that the files you are having problems with are damaged.

Thanks for help. I will try that software.

I think the problem don't come from "damaged file", the files come from different sources and they all can play back normally.
