Potplayer (a media player) can play quite badly damaged clips, and it's Video Recorder, will record to uncompressed AVI (I use YV12 raw),
and PCM(Raw) for re-encoding.
I switch off any/all filtering options, and make sure to set system record volume to a central values.
Sections that are too badly corrupt will result in static section that can be later trimmed out using eg VDub.
PotPlayer is a bit "Persona non grata" on this site, but is the only software that I'm aware of that is almost bullet proof
when dealing with video corruption.
EDIT: Get recent version from VideoHelp.
