I have a geforce 6150 motherboard and would like to get HDTV out going on it with MythTV. I know that I will have trouble getting good HDTV out. I was wonder what options I should use to make it sufficient. What should I put in my Xorg.conf and in my rendering options?

Thanks

No one has this working?

I hope that I can answer you on this topic after this weekend. I currently have my GeForce 6150 driving my Sony KF-50WE610 thru DVI. I have 2 modelines, one at 1280x720 with overscan, another at 1176x664 with no overscan. I use the 1176x664 modeline with KDE and it looks good.

The pcHDTV is installed; I just need hookup the antenna and install MythTV and see what I get. Hopefully this weekend.

For me, the alternative at the moment is to use Twinview on my MSI K8NGM2-FID 6150-based board.
There is significant 'tearing' of the video, but at least it allows me to view the shows using 'xv' video acceleration.
NVIDIA Driver version 1.8178

Well the problem for me is not getting the modelines working. The problem for me is the HDTV accelleration. Because the 8150 doesn't support video overlay, my CPU usage is really high, unnacceptable. I'll reply in a little while with more info.

I read this a HOWTO, but I don't know how to enable it.

Applications such as MythTV will use OpenGL and enabled V-Sync to get most if not all smoothness back, however, if an application depends on video overlay you may have problems

Ok so I was looking around the Nvnews forums and found this, but I think if I continue having problems I might as well install windows and get it to work for real. Which is really frustrating because I really like MythTv

Section "Monitor"
Option "RenderAccel" "True"

and also use this as your rendering options

"-vo gl2 -dr"

nVidia has admitted to a known bug that XVMC is broken with the latest drivers. Hopefully will be fixed with the next version.

Have you read thru this thread? http://www.nvnews.net/vbulletin/showthread.php?t=57791

Quite lengthy, but lots of info on the board and linux.

I tried that for mplayer. If you use different -vo gl2:yuv=[1-4] , you'll get different CPU usage. I had a different type of flickering, where the image would "black out" here and there. A little annoying but not that much different than DVI-tearing. Using GL, my mplayer cpu usage would come close to 100% with both the cpu and video percentage, sometimes causing dropped frames, ie, 55% cpu/40% video. With 'xv', the usage was more like 20% cpu, 5% video with less dropped frames a/v sync problems. AMD64 3200+.

Another thing that helped is the -vc arguments. I found that -vc ffmpeg12 worked best for my situation. Without this, the default video codec was mpegpes, which caused mplayer to use a software based scaler/colorspace conversion.

I read this a HOWTO, but I don't know how to enable it.

From what I was experiencing, myth would only use the opengl v-sync for syncing. It still used xv for video output. The problem was xv didn't work at all and locks up the system if using single display through DVI/Component ports at high resolutions (thru the VGA port, everything works fine).

OK. I got MythTV working and am getting HDTV on my Sony Wega at 720p. The picture is super sharp as long as nothing is moving. But if something moves across the screen, then the picture gets kind stripey. Is this the "DVI-tearing" mentioned above? CPU is a Athlon 64 3500.

I really want to get this working. Windows is not an option right now, because I bought the pcHDTV as my tuner.

The -vo options discussed above talk about mplayer. Is that the player that MythTV uses or does it use its own built-in player?

Hopefully nVidia will have new drivers soon that will incorporate XvMC.

Unfortunately, that setting only applies to the primary display, which in a twinview configuration is the VGA port. There is currently no way to designate the DVI port as primary in a twinview config.

The DVI tearing looks more like two halves not quite in sync. Usually a top section and a bottom section.
You might be seeing interlacing, which would occur if you're viewing 1080i on your 720p.

Instead of using the built in player in myth (ie, Watch TV, Watch Recordings), you can use Watch Videos, which uses an external video player, which can be mplayer. In the settings area, you can specify the program name and arguments. This is pretty much how I view the recordings, since mplayer is 'smoother' in playback versus the built in myth player (alot of buffering and frame drops).

Have a look at this pic (http://www.phoronix.com/images/picture.php?id=0&image=nvidia_8751_03_lrg) from Phoronix's sneak peak of some beta drivers. Obviously they tested with only the one display, but I get the feeling that you would be able to designate if using twinview.

Do you have another URL for that pic, or perhaps an associated article? It just shows a Phoronix logo when I go there.

It was from this article (http://www.phoronix.com/scan.php?page=article&item=420&num=1), but it looks like they have (without posting any notice) taken it down, along with ~10 other pics of the nvidia-settings for the v1.0-8751 beta drivers. There are only three photos still remaining out of the original lot. Perhaps withdrawn at nVidia's request? I imagine they would comply as they seem to have good relations with both nVidia and ATI.

Anyway, the pic I linked to was of the "X Server XVideo Settings” section. Within it was the familiar 'Sync to VBlank' checkbox option. Listed below that option, and the only other item presented in the section, was an "apply_that_(Sync_to_VBlank)_setting_to_this_display" type checkbox option....which was labeled with the lone Acer monitor that they had attached to the video adapter.

This thread has me a bit concerned... I was just about to pull the trigger on a 6150/430 board (the ABit NF-M2-nview), along with an Athlod 4600+ (2.4GHz) and a pcHDTV tuner.

Has anyone gotten clear HD playback on such a system?

If the onboard video driver taxes the cpu too much, perhaps going dual core would help... anyone have experience there?

Thanks for any help.

I too am getting close to buying hardware for a MythTV box but am having trouble deciding what will work.

I'm using a 6100 board and I had problems until I disabled sync to vblank everywhere in nv-settings. Only left sync to display device in X Video settings. Works fine now. The 6150 should do better since it's rated for HD. Nvidia 8762 driver using XvMC, and Bob.

I'm running an Asus 6150 / AMD64 3200+ and KnoppMyth upgraded to MythTV 0.20. The only problem I have is a conflict between the on-board audio and Fusion 5 Gold tuner. It appears to be a driver issue. Using a PCI sound card, record and playback are both smooth with the latest NVidia drivers.

Hope this helps.

Can some body please share the modlines for Nvidia 6150 connected to Maxent 50" for 1366 * 768 ( or near by resolution 1360, 1368 etc)

Also if you can tell what resolution you use then that would be even better.
thanks

Ok, I'm having trouble getting rid of tearing too. I have the 6100 405. I'm running with a 1080i CRT RPTV. It seems that no matter what settings I choose, I get bad tearing. I do not have deinterlacing enabled. Is it possible to get a 1080i source displayed a 1080i display without tearing and without enabling deinterlacing?

I have a geforce 6150 motherboard and would like to get HDTV out going on it with MythTV. I know that I will have trouble getting good HDTV out. I was wonder what options I should use to make it sufficient. What should I put in my Xorg.conf and in my rendering options?

I've got both a 6100 and 6150 and get good playback with both. The 6150 is hooked to an Olevia 427V KCD HDTV via the vga port. TV playback is set to standard using kernel deinterlacing. Both these are using an X2 3800+ cpu at stock speed. Even works well using PIP both HD. I don't use any special modelines. On the one with the HDTV I just use the standard 1280x720 res. and the TV adjusts it to full screen native mode (1366x768).

I have my integrated 6150 running through VGA and so far 1080p .mpg works almost perfectly with no interlacing artifacts or frame skipping (I've tried using both xv and gl2 as vo). 720p material looks beautiful and runs without any hitches whatsoever.
