PSP h.264 has an audio and video file after conversion is complete!!!

[chipsahoy1]

i have been encountering a strange thing when ffmpegx 0.0.9v is finished converting my MTR vob file. I choose the psp h.264 conversion method and when the process is complete, i have 2 separate files...one audio and the other video. has anyone been having this problem? it doesn't do this everytime, but it seems like ffmpegx 0.0.9v has some inconsistent conversion issues. any help solving this issue would be greatly appreciated. thanks.

These are temporary files which will disappear when the process is finished, unless an error interrupts it before the end.

thanks major....
but what kind of error? it seems that i'm not the only one having this issue. and it there are times when this doesn't happen. i don't do anything different with the successful conversions from the unsuccessful ones. any suggestions? thanks.
