Cropping 16:10 Video corruption

[elbeasto]

If I crop video to 16:10 the video becomes corrupted.

This is on a new Samsung 2433BW Plus monitor & a new GTX 470 video card. It used to work perfectly when running on my old 226BW & GTX 260.





Any suggestions?

Thanks

How do you crop?

[elbeasto]

Video>Crop>16:10

Does it help if you change video output module?

[elbeasto]

No doesn't help.

The video plays fine at every other aspect ratio except 16:10 which happens to be the AR of my monitor.

Does anyone know if the Samsung 2443BW Plus has 1:1 pixel mapping & if it doesn't would that case the problem?

Thanks

Monitor isn't the problem. This is software issue.

Monitor isn't the problem. This is software issue.

So you would definitely blame my version of VLC (1.0.5 Goldeneye) rather than my monitor?

[VLC_help]

Yes. Does VLC 1.1.0 work any better?

[elbeasto]

Yes. Does VLC 1.1.0 work any better?

Unfortunately no, I installed the new version (1.1.0 Luggage) last night & the problem is still there.

However I do have some additional info that might help.

The only files affected with this problem are ".nuv" files which have been transcoded to this format on my mythtv computer. Also, it only happens while viewing in full screen mode.

My ".avi" Divx & Xvid files seem to be OK.

Thanks for the replies thus far.

[VLC_help]

Could you share us one problematic file that we could use to replicate the problem?

[elbeasto]

OK, I'll have to transcode a small segment of video otherwise the file will be too large to transfer.

[elbeasto]

Another bit of info that might come in useful.

I noticed that the video corruption did not occur with television shows recorded from different channels. Transcoded video from channel 10 does corrupt but shows from channel 99GO! do not.

I'm pretty sure that the digital stations in Australia all use different ways of broadcasting their content. So far I have found that the corruption occurs on channel Ten Digital, Seven Digital & ABC1 Digital but not on 99GO!

Cheers

File a bug with a small sample.

[elbeasto]

Will do, I'm just trying to transcode something that will be a sensible file size as the average half hour show transcodes to about 450MB.

[VLC_help]

Just binary cut 50 megs from the beginning of the file.

Since installing the current version "vlc-1.1.7-win32" I haven't experienced the issue at all.

Thanks very much to the VLC developers and everyone that helped in the forums here.

Unfortunately I am experiencing this bug again, I have not changed the player version since it was working fine but have recently updated my nvidia drivers to "285.62-desktop-win7-winvista-64bit-english-whql".

The distorted video appears when cropping to either 16:10 or 5:3

I'll try going back to the drivers I had installed before these and report back.

My current monitor and video cards are: Dell U3011 & EVGA GTX580 SLI (happens with SLI disabled).

Thanks

[elbeasto]

It's definitely the nvidia drivers that are responsible for this problem.

After uninstalling the latest driver 285.62 and reinstalling driver version 280.26, the problem has gone away.

I installed the latest driver again just to be sure and sure enough the problem came back.

So I suppose this is a problem that I have to take up with nvidia and not VLC?

Thanks

[Jean-Baptiste Kempf]

Probably, yes.
