Hi everyone, just discovered that my trusty old G550 can only do 1280x1024 via the DVI output .... damn it !!
Anyone have any recommendations for a card which will work with softdevice and directfb or vidix to do digital 1080p and 1080i resolution output via DVI? I will be connecting it via a DVI-HDMI converter cable to a Toshiba 62CM9UA rear projection TV.
I am after the most stable card with the best playback quality I can get and don't mind spending a few hundred dollars to get the right one.
Thanks for your help.
Regards Anthony.

Hi,
cheap ATI and NVIDIA cards are good for HD video output (esp. NVIDIA because you can get MPEG-2 acceleration working with the binary drivers). The cheapest passively cooled cards work as well for video playback on Linux as the high-end models, so don't pay over 40 euros for one. However, these cards work best through the X.org drivers, so you're better off with vdr-xineliboutput than with softdevice. Anyway, Xine offers better deinterlacers, which are very important for playback quality with such displays as yours.

The cheapest way is to go into a shop and buy a simple set top box. So get you both: closed hardware and closed source. Most advantage is: As you've paid, you'll get paid professional service in case you have a problem.

Hello all. I have battled with my hardware and software for a week or two, only with partial success. Then I just lost my motivation. Now my Motivation Fairy appeared to me again. She gave good advice: ask for help. :)
I am currently using my VDR 1.4 with the composite video output of my FF Hauppauge DVB-S nexus card.
I also have a Matrox G550 card (with DVI output) installed in my vdr box. My dream is to use a DVI-HDMI adapter and a 5m HDMI cable to my HD video projector. I am not interested in HDTV, but I just want my video signal in good shape into my Panasonic PT-AE900. It is such a good projector, and it is a shame to use composite video with it. :) Furthermore, I have some grounding problems with the looong signal cables...
The problem is, I don't want to give up the good olde composite video, because my TV needs it. I am not going to use the projector all the time for just watching TV shows. So I need both video outputs, and the composite is more important than DVI, because my TV simply does not know about HDMI or DVI.
I think this means that softdevice is out of question. Am I right? I played a bit with directFB and a program called "fbtv". It is able to grab video from the dvb device and transfer it into my G550 DVI output. Fbtv has some features that I don't need or like, but hey, it's a start. I know this should be possible! I just could not configure my framebuffer correctly to generate an interlaced PAL signal to DVI/HDMI, with frame sync.
I never got it to work with my projector, but i managed to get a non-synced-to-frames picture to my DVI connected lcd (ViewSonic VP201b). The picture was quite ok, but any motion in the screen had distortion because of the out-of-sync frame changes. Sorry if I am using wrong terms here. :)
I am very thankful of any advice you can provide. Do anyone have a similar setup?

Perhaps not the cheapest one. I just upgraded FX 5200 to 6200, both passive cooled low end cards. The HW deinterlacer for progressive output (720p in my case) is much better in 6xxx and 7xxx nvidias imho. In FX 5200 it was not really usable. With interlaced mode the case would be different but there the problem with cheapest cards to get 1080i over DVI.
I'm not yet 100% satisfied with HW xvmc + de-interlacing with the 6200. The load in system is very low, only some % and the system is running really cool but I get video flicker (some black lines for a fraction of second) with DVB subtitles. Also the OSD has some very small vertical judder probably due to deinterlacing. Any ideas to fix these with x.org and xine settings?
Cheers, Seppo
