Repairing Damaged Dvr-ms Files, damaged by a system crash during capture

[Ext User(Rod Speed)]

Had a system crash while capturing to dvr-ms files using WebScheduler.

Those files are unplayable in every player I have tried, all the obvious
players.

With previous problems seen when running out of hard drive space,
I have been able to edit those files with dvrmsEdit, but it wont open
these.

Why does nice open software like WebScheduler use an evil DRM-ified
format like dvr-ms ?

DVR-MS is apparently mpeg2 codec in an ASF format file, so try some ASF
tools. Maybe a converter, rather than a player, will fix it.

Tried dvrtompg ?

You may want to record as a 'program stream' in future. Its corruption
resistant, similar to the broadcast stream, but will play in any good
player software.

It doesnt, that is just one of the formats it can capture to.

Yeah, I should have said that I had tried that one. It fails.

Yeah, have been considering that given the dearth
of utes to repair damaged dvr-ms format files.

I have found that Media Fixer is happy to repair a good dvr-ms file.
You do have to rename it to mpg and then back to dvr-ms again once
its repaired the file, but it looks like it might well be what I need.

Unfortunately the damaged dvr-ms files are much bigger than the
known good one and Media Fixer is pretty damned slow, took all
morning to massage a 45 min capture on the relatively low horsepower
PVR, so it remains to be seen if it will in fact fix a bad one too.

I dont actually have a small damaged one and no obvious
way to make a smaller one to test since none of the dvr-ms
file editors will even open the damaged ones. I'm about to
try one chopped up with a binary file editor.

I'm about to move the 120G drive to the decent horsepower
system and see how that goes on that since I need to massage
an avi into a traditional DVD format too for a dinosaur who
only has a traditional DVD player that wont play avis.

That didnt work, the damaged file isnt
any better 'repaired' than the original was.
