It's my understanding that it is the pixel rate that is doubled to meet the minimum bandwidth requirement of 25Mpixels/sec for hdmi. That is pixels are repeated hence doubling the apparent horizontal resolution. This is always the case for the 480i and 576i modes. The modeline you need should be ba

[vdr] 576i output on DVI->HDMI?

2008-07-15 Thread Jukka Vaisanen
With all the recent talk about deinterlacing, I was wondering if it's now possible to get 576i output over DVI->HDMI from xine-based output devices for VDR? I was a dxr3 user for a long time and the deinterlacing offered by A/V hardware never gave me any issues.. Now I have an A/V receiver with a
