TV Tearing with 8762
 
I'm using TV out onto a HD1080i TV and I notice some small amount of tearing or strips of image with a break or alignment problem. On previous threads I have been lead to believe this is a side affect of VSycBlank option
Note here is my nvidia config below.
Has has this been fixed in new 8774 driver? or is there some other setting to correct this ?

Re: TV Tearing with 8762
 
anyone,
Note I only get tearing on fast moving video so I'm wondering if this is the best I can expect or should I get better performance.
Note my card is a NV 6200 TC on a AMD 3000 CPU

Actually, at least in theory, you _should_ sync to vblank.
That is, the player should update the video buffer during the vertical blanking, so no half new/half old buffer is rendered by the video output unit.

In addition to this, the player (or something else), should to double buffering (an option of mplayer, AFAIK).

Hope this helps.
