Windows XP bug with large .avi files, What about capture?

[Pitou]

Hello,

I just saw a fix for win XP on this site (can't remember the link) about problem deleting incomplete avi files. This is caused by explorer scanning the entire avi file, trying to get to the index at the end.

I have a problem while capturing VHS blue screen. The thing is that it drops a couple of frames about every hour (about each 100000 frames).

To solve that I installed win2000 instead and no more problem since. I capture over 3 hours without a single drop.

Since while capturing, it's 100% sure that the avi file is incomplete, could it be the bug mentioned above, that explorer scans the entire file trying to reach the end, leading to a burst of disk activity(because I see some anormal disk activity in that particular moment), so dropping frames

btw, I'm aware of everything about capturing (HD speed, BG tasks, disabling everything in XP, etc... It's not the problem, it's not my system since it works in win2000)

Any opinions or comments on that?

Thanks.

You're talking of this

Registry Edit for WinXP Prof. If unable to delete .avi’s from Explorer

Delete the lowest folder …. leave the upper structure and just delete...\InProcServer32

Start regedit and remove the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{87D62D9 4-71B3-4b9a-9489-5FE6850DC73E}\InProcServer32



I'm not aware of that being an issue in the handler in w2k

[Pitou]

Yes.

But it's more than having problems to delete files.

It's really a thing about scanning an entire broken avi file, to try to reach the end. (Index)

Do you think it can have an impact on capture??

I don't want to re-install XP just to do the test.

Especially when you choose "details" instead of "Icons" in the explorer window, when displaying your files.

Maybe it tries to refresh the data and then starts to scan the .avi file for some seconds. And since the avi file is broken or incomplete (it's capturing!!!), the explorer works hard and produce some drops due to some extensive disk activity.

Hi,

First of all are your harddisk NTFS formated? Windows can only handle avis less than 4GB if they are not NTFS formated. How are you creating your avis?

Do you have problems recording any sort of avi short or long i.e. it wont close properly and you end up with a corrupt avi.

If so your avi sub system might be shot.

I have a registry fix which fixed a similar problem I had it might help. Copy and paste it into a text file and rename the extension to .reg

I use NTFS and Virtual VCR to capture to avi using huffyuv.

I don't really have problem with short avis, but, every hour (at about 100000 frames captured) it drops a couple. So at about 100000, 200000, 300000 frames, it drops a couple.

Thanks for the registry I'll give it a try.

Are you capturing to an empty drive? Do you have anything set up to kick in once an hour i.e screensaver, virus checker, power down of computer.

[Pitou]

Yes, I'capturing to an dedicated empty drive

I don't have anything that runs every hour. I thought it was windows itself so I booted with all services and everything else disabled. Even with a clean format and install of windows XP.

btw, keep in mind that it works with win2000, which I'm using at the moment.

Thx.

Pitou.

Try disabling indexing on your drives. Right click on the drive you want and go to properties. There an indexing box there. Do you have service pack 1 installed?

Have you tried the generic drivers for you capture card. Can be found in tools section. Do you have your proper drivers installed i.e from manufacturers website and not relying on the ones built into XP.
