Watching other types of videofiles on GBPVR

you will probably have some problems with tearing if you dont use overlay mode. if you are looking for a cheap card I suggest ati, their TV-out is much easier to configure (click the video mode button) Nvidia's can be rather finicky. I remember having trouble getting it to look good on my TV before I got my HDTV. but I havnt used the new drivers, they might be better.

Thanks for all your advices.
I have video playing from my NVIDIA card and it works. But some problems still: When I use a resolution of 720x576 for PAL that we use in norway the video is placed to the right side of the screen. Using 800x600 it is placed in the middle of the screen, but it does not fill the whole screen. The colours of the GBPVR interface is rather bad and it jitters a bit. This may be because the card is old? On the positive side I get video in video and thats cool. Any more advices?
as ted said, set render to overlay or try VMR custom. overlay will give deeper colours (I think)
you can use the settings in the nvidia drivers to move and expand the screen to fit your tv correctly. [edit] sorry I didn;t ready accurately. If the interface is jittery/washed out then you can only play with the nvidia settings (make sure you have the latest drivers). the advice above was for mpeg playback. [edit2] I would recommend you buy a good svideo -- SCART cable (rather than the really cheap ones). I noticed quite a big improvement when I did this. However in all honestly, I think you should think about getting another video card. For what it is worth: I am very happy with my old ATI 9600 PRO (silent heatsink) but a newer card might be better, depending on your budget. Also (without wanting to go too far off topic) think about whether noise is an issue or not and if it is, choose a graphics card that doesn;t have a fan (like the 6600GT I mentioned earlier)
âIf this is the way Queen Victoria treats her prisoners, she doesn't deserve to have any.â
there is a setting that changes whether its interlaced etc that can get rid of the jitters or make them worse
nviewDisplay settings >device settings>select tv format>480p/480i/576i there are more but these are the ones that would suit svideo screen resolutions & refresh rates then you can also add custom settings and chage the refresh rate either 50hz 60hz 75hz 100hz either go in 25s or 30s depending on ntsc or pal may stop some of the flicker as for card i used to use ati but since pure video come out i have been very happy with the nvidia cards same deal no fan and plus i like the fact it has more setting to change the picture i guess it just depends on if you like tuning or are just happy with its close enough

OR you could look for things posted by csy he is pretty much a guru about that stuff, or at least the threads he posts in should have some good information  good luck gEd Wrote:as ted said, set render to overlay or try VMR custom. overlay will give deeper colours (I think) well the first thing that we need to establish is that video (DVD for reference) levels for colors are not the same as those on the computer (RGB), DVD is 16-235, while RGB are 0-255. ok so the major difference in color representation between VMR and overlay is that VMR will just pass all of the color information without any manipulation while overlay will stretch the DVD color levels to match RGB, which can lead to artifacts, as well as loss of sub-picture information that they pack into the extra bits. AVSForum thread giving more detail also a good read in generalhttp://www.avsforum.com/avs-vb/showthread.php?t=523614 I use a 9600 and it has been a champ :p never really had any problems with it, video out looks nice, and it drives my HDTV no problem (for now) cheers sub Wrote:Are you trying to make sure I get nothing done today?

well he doesnt have a ati card his is an old nvidia card
so overlay will probably work better than vmr anyway so you can quote all the ins and outs and confuse the poor guy all you like try both overlay and vmr but from my experience it seems you get jumpy palyback from vmr im not saying dont use vmr im saying try them all then test yeah ive read all the reasons why one should be better but what it comes down to is what works

stustunz Wrote:well he doesnt have a ati card his is an old nvidia card hey now, I feel that more information is better than too little. and we had already gone over what would probably happen. but I can elaborate more if it makes you feel better, since I did have an nvidia card in my PVR at one time. so I prefer VMR, since it also lets you do better aspect ratio transformations, overlay is limited to the size of the screen (0-1) but VMR can stretch outside the screen (<0-1<) so you can do things like get rid of letterboxing... or just that annoying one or two pixels of CC information at the top of the screen :p I personally use VMR7 on my card (ATI) , since VMR9 was jumpy. when I had my NVIDIA card, it was an FX5200, and I had to use overlay mode, because I got tearing on the screen, it was intermittent, and wasnt really that bad, but if there was a slow horizontal pan, you could really see it. If you dont know what tearing looks like, it is a loss of sync when displaying the video, so part of the screen will be behind the rest, for me it looked like a jagged diagonal line (think stairsteps) where one side would be a frame or two off from the other. now, when it comes to setting up the video output, you are going to want the PAL resolution (576? x 720) interlaced, at 50Hz. with as little flicker correction as you can stand, and you are probably going to have to muck with the colors, but that is a personal preference. good luck

The fact that I havent got this to work optimally makes me think that much information is better than less.
Now I have two days and a lot of advices to try out. It's a pity that I havent got the time until next week :-( Thaks a lot for all your helpfull comments guys!
EDit i removed this line as it was wrong and i am sorry shouldnt write thing when you first wake up
s as for interlaced and the 720x 576 i run 720x420p refresh 100hz which is the same really but just progressive as my tv is so what im trying to say is you cant tell him he has to have 720x576i because it will depend on his tv |
