Hi,

I have a Geforce4-Ti4400 Card manufactured by MSI, it has a Video In Interface, and I am using the nvidia WDM capture drivers.

However, when I try to capture a video in PAL (I live in Germany, PAL is standard here), the bottom of my input video coming from a vcr or TV is cut off.

There is a program called WinProducer, it offers a PAL-Switch and is capable of displaying the whole picture when PAL is selected, but I cannot capture with this program due to a stupid low-diskspace warning, but that's not the problem here...

However, I want to capture a whole PAL video without the bottom being cut in Virtual Dub, how can I do it? What settings need to be made in VDub, or the Video Drivers? I am searching for a PAL-checkbox, but I can't find one :-(

Please, help if you can.

Thank you very much in advance.

Regards,

Jackie

I'm having this problem as well. I've only tried two nvidia WDM versions so far (1.11 and 2.13) and I'm about to give 1.08 a go. If I find a solution, I'll post it here.

It seems that VDub(Mod) doesn't like 768x576, and I have a feeling that it's being cut off because it wants to use 720x480 instead, and not being the right resolution results in it cutting the bottom off and inserting black bars on each side. 640x480 has no black bars on the side but it's still cutting off the bottom of the video (about one sixth of the total frame, if I had to guess.)

If anyone else already has a solution to this I'd be grateful if they could post it here :)

Edit: SUCCESS!
What is required is to get out regedit, search for keys named "VideoStandard" and change their value to PAL.

Not being able to post an attachment, I'll put the contents of the registry patch here:

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0027]
"VideoStandard"="PAL"

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0027]
"VideoStandard"="PAL"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0027]
"VideoStandard"="PAL"

The one in CurrentControlSet is probably the only one worth bothering with...
