If someone wants to donate an nvidia card to me, then I'll fix it.

Sub,
Thanks for your efforts in looking into this. The link I posted for digitalwatch source was actually for the version 2.0+ which is significantly different to the 0.726bda version I had been using with VMR9. I liked this appplication because you can exactly define the filter chains used on the output side of things via the video.ini and audio.ini files. Here is a link http://nate.dynalias.net/DigitalWatch/BD...tible.html to the latest source codes I can find. These versions appear identical in output functionality ie. zoom and aspect control since 0.701 onwards. Hope it may be of some use. Can somebody confirm this issue occurs with a geforce 6200 AGP. I was under the impression there are some major differences between the video processors of agp and pci-e variants. See here: http://www.nvidia.com/page/purevideo_support.html I have verified the problem exists on the following pci-e variants 6600, 6600GT, 7300GS and 7600GT. Daza

See here: http://www.nvidia.com/page/purevideo_support.htmlI've only got AGP motherboard, so hopefully its also a issue affecting the Nvidia 6200 AGP. If so, I should be able to resolve the issue with the card Limiter has kindly offered to donate.

Interesting thread with what appears to be the same bug. http://www.dvbviewer.com/forum/index.php...opic=11555

Quote:Sub,Does it actually show any OSD graphics mixed with the video like GB-PVR? Looking at that old 0724 code, it looks like they're setting it to always stretch to fill the window, then resizing the window to the appropriate shape for the aspect ratio. This wouldnt be an option for GB-PVR, since we need to mix the OSD into the same window. As an example of what I mean, if I used the same approach, and resized the video window to letterbox a 16:9 video for disaply on a 4:3 tv (adding blackbars top and botton), then the OSD information normally displayed at the bottom would be moved up the screen to above the bottom black bar. Make sense?

From what I know about it, it does just sound like a bug in the nvidia drivers, when DVXA is enabled. It seems to kick in when the developer makes use of the IVMRMixerControl9->SetOutputRect() API with any values other than 0,0,1,1. I'll try to work around it if I can, but I dont know if the same feature can be achieved any other way, while retaining the OSD mixing.

Sub,
Just tried another very simple app called dvrviewer available here http://mediapix-australia.com/htpc/DVRview/with source code. This uses vmr9 and apha blending of the OSD and does not suffer any problems during aspect ratio changes or when zoomed. See screen shots taken. Daza

My aspect ratio kept scaling to letterbox on my 4x3 screen. I removed the autoconfig line from the config as sub suggested and it displays full screen now but its too tall. It cuts off at top and bottom when watching live tv.
When watching a recorded source it scales just fine? Any ideas? I tried using vr9, vr7 and overlay all have the same results. This was never an issue before the latest release. I have an AGP nvidia 5700 |
