A new driver apparently came out on Dec 5. I was wondering if anyone had tried it and if it solved the 1080i split screen problem.

folks have been chewing them over in this thread: http://mysettopbox.tv/phpBB2/viewtopic.php?t=7244&highlight=8174

according to what I read in nvnews, it didn't work. Nvidia had assigned an error number.

working fine for me in 1080i right now using a vga -> component converter. It didn't like my 1080i@59.4 (or whatever it is) modeline, but 1080i@60 works fine.

Installed 8174 and indeed it worked on 1080i using vga -> component adapter. It may still contain the xv quality bug though. When I view SD contents from PVR-250 input, OSD menu still had very poor resolution. Anyone else can confirm?

Crap! Fix one thing and break another...

Myth Menu and the X desktop are now rock solid. But I can't even play back standard def programs without stuttering. I am temporarily trying it out with XVMC which seems to allow me to actually watch stuff. From what I can tell the picture actually looks better.

nonpro: I can confirm that SD OSD menus look like crap, but I'm talking about SD programs from ATSC, not from an analog card.

Xsecrets: when you say it didn't like your modeline what exactly did you mean? Please tell me it was stuttering problems and I just need to fix my modeline. Bedtime for me I will try playing more if I get time tomorrow.

well it would manifest itself differently on different videos some would just put a picture on the screen with no motion, but fluid sound. some would have really wacked out colors. There may have been some stuttering there too, I don't know I quickly tried the other modeline and wiped my brow

That new nVidia driver certainly looks good on my system. I notice a lack of flickering on single-pixel lines and high-def motion is very smooth. The new drivers might be just a tad less "sharp" than the previous ones, tho.

One thing I definitely noticed is that the new 8174 driver is a cpu-sucking monster. Using "top" I see about 85% of my P4/HT/3GHz processor wiped out during playback. The 6629 driver took about half that.

Liv2cod: Do you have 'use opengl sync for timing' enabled in your TV Playback settings? This drove my CPU usage way up when I installed the 8174 drivers, althought it was fine on the 6xxx and 7xxx series. Disabling it left me with my regular loads for xvmc and xv output.

Y'know... I probably are using OpenGL sync. I'll be darned if I can find that setting right now. But I think it's necessary to use that setting in my case. I have 1080i content being displayed on an interlaced set. For my setup, I'm pretty sure I leave all "deinterlacing" turned off and enable OpenGL sync so it can sync the high and low fields of the interlaced display.

I did find the "closed caption" setting was turned on for the vertical blanking interval. I turned that off and picked up another 5-8% so my cpu is now "only" 78% used up during playback!

But it's worth it to have a better picture.

So OpenGL sync is for interlaced content? I could never figure out what difference it made when I was outputting 720p or 1080i to my 1080i set. I also had the settings checked for video overlay vertical sync in nvidia-settings. Does that compensate for a lack of opengl sync?

Could someone point me to where this setting actually is. Or is it something new to R5A26???

benjohnson: it was new with R5A22 and R5A26, where it's located at the same screen as 'use XvMC for playback' in TV Settings->Playback

If you have "Use OpenGL sync for timing", but have -vsync in your modeline, (thus turning off vsync) which takes precedence? Will vertical syncing be on or off?

Modeline -vsync does not turn it off. It sets it to use the negative-going edge for sync instead of the positive-going edge (+vsync). But vsync is always needed from the perspective of the driver.
