HOW did it possibly become corrupt ????

[StoneColdWhat]

Ok so I have some files some captured files and some encoded to mpg from avi. When I encoded them they were fine and I checked them ( this was last week ) then all of as sudden when I play them today they have parts that isn't even part of the original source! So it would be playing then play something totally different. The common thing between these files is that they're all MPG2, could it be a bad codec ? I've recently uninstalled a codec pack and codecs that I thought were not useful. Right now all I have installed is Sticky's mpg2 codec. Mmmm... a little more insight on the issue, this one file I encoded a few weeks back had something that I encoded YESTERDAY. Yeah I don't know what the problem might be please help me out, I'm totally lost.

try play with videolan. it has it owns codecs.

Overly fragmented hard drive, or IDE controller drivers are defective or wrong for your system.

Two of many possibilities.

When was the last time you ran a disk check or defragmented ?

OK Guys heres exactly what happened, on saturday my power supply died and my mobo was on the verge of going as well so I took it in for repairs and got a new power supply and a different board with basically the same chipset.

Lordsmurf: if you think it is the IDE controller being defective, could you be a little more specific ? The guy did mention something about the IDE but I din't remember what, if you suspect this is the problem then I'll call him up and ask what he encountered.

Gun: Hmmmm disc check or defrag I would say a few months back, I've never had any problems with it until now. I suspect its the mother switch but if it is the disc check or defrag, after doing that my file will be back to normal ?

Your power supply failing has corrupted the data on your hard drive. Hard drive was probably writing to disk when failure occured. I dont think you're gonna be able to retrieve the files intact.

The diskcheck will tell you if you screwed the disk while writing. The defrag will clean up the disk and stop any errors coming from too much fragmentation. I wasn't pointing at either as the fault, more as part of a possible solution. Of course, that was before you decided to tell us about a few minor things, like the power supply burning out and changing the motherboard.

Let me ask you something. You go to the doctor with a sore leg. Do you just tell him you have a sore leg, or do you also tell him that a bus ran over it ? Would you consider the bus part to be vital information ?

When I first installed Windows XP on my previously Windows ME computer (fresh install, reformat, not upgrade), the XP install of the IDE drivers for my expansion card was wrong. It would butcher files and make a big mess similar to what you described. Replacing the drivers with ones from the company's web site fixed it.

Another time, a computer developed some sort of problem after a power surge, and I was forced to repair windows. When it restarted, the drivers were some sort of crap defaults that had this sort of errors. Again, download from that company's site (motherboard IDE drivers, this time), and it was fine.

An yet again, when I swapped out a motherboard without reformatting the disk and re-installing windows, I had an IDE conflict that did not go away until I formatted and started over.

This is very likely your issue.

It will sneak up on you like heart desease. I do it every week religiously. You'd be shocked as to how much video work will frag your drives. I ran scan disk a few times on an external drive that was having "write to" problems. Everytime I re-started my PC it would trigger the scan disc for that drive, The scan and repair finally took and it repaired a ton of bad sectors. All is fine now.

I sort of laugh when people say " Everything was fine before,,," These things will happen many times with no physical warnings but believe me, everything was definitely not fine.

The bad news, unless someone else has some other suggestion, I trhink your files are shot for good. Redo them. Would not be the first time I've have to do that.

Well at the time the power supply died I wasn't writing to the files in anyway nor playing them, was playing a game at the time.

lordsmurf When you say your expansion card needed IDE drivers from
the company's site, what kinda card was it ? The only expansion card I have is some PCI game controller plugin that I don't use, and my video card the 9800 AIW. I"m going to try and find the IDE drivers for my motherboard...

And yeah I ran disc defrag on the drives and.. thats that, going to run scan disc in a bit.

My Old mobo was Gigabyte 7n400-l, now its Asus A7N9X-E DELUXE.

Also it seems like only my mpg files were affected with this weird corruption.
