can't playback 4.02GB (12hr) divx recording created using pinnacle mediacenter

i used pinnacle mediacenter 4.1 to record a tv broadcast using the divx codec (divx portable profile). usually the recordings, albeit shorter work fine, but right at the end of the recording process i was watching a dvd, it was paused and using very little processing power at the time the computer was saving the file. however something must have crashed because when i tried accessing the file, i kept getting prompted that the recorded file is currently in use. so i rebooted the computer and have been trying to open it since but no luck. “Windows Media Player encountered a problem while playing the file. For additional assistance, click Web Help."

i only need to access a part of this file since there was going to be a 30 min or 1hr show on at some point during those 12 hours but since i didn’t know what time i recorded the whole stretch and figured i’d edit out the part i needed later. i tried using dr divx (both 1.0.6 and 2.0) on another computer to encode the file but both versions rejected it. gspot states: “Note: 4.02 GB unneeded bytes at end of file AVI v1.0”

i know that the pinnacle saves data to disk as it records the live broadcast (the file grows as time passes during recording) so that means if anything is corrupt, it’s probably the end of the file which i don’t need anyways. so how can i recover some of the data in this file? any assistance would be most appreciated. thanks in advance.

with the version 1 of the avi format the limitation of the size is 4 GB.
You have to use AVI openDML; try with virtual dub to recover the file and save it again.
