[quote="Xsecrets"]my suggestion go find a modeline generator on the web, I always have to google for them, and create yourself a 640x480 60hz modeline. you can use 30-50 as the horz should be fine. and try that.[/quote]
So the XF86Config-4 file without the "NTSC-M" but with the "HD480i" line should work fine if I can find the correct modeline entry?
Is there an online DB where one can look up specs/modelines for known TVs?

thanks tjc,
I'm afraid that this config file doesn't work for me (because none of the modelines worked).
I'm stumped..

I reinstalled the driver again and got tjc's config file to work. Unfortunately I'm still getting the soft picture.

If you're using that "as is" you're probably running at 800x600 which means that it's doing scaling. You can check this in your log file. Look for a line like this: Quote: (II) NVIDIA(0): Setting mode "800x600" To fix that go into the "Screen" section and change all the lines that say: Code: Modes "800x600" "640x480" to be just Code: Modes "640x480" I've done this before and know that it works with the modelines there.

thanks tjc - I was able to get the display running 640x480 (I also have the LIVETV profile running at 640x480). I'm convinved that the picture is looking better but I've still got a little blur left . I'm still playing around with the nvidia-settings. BTW are you using any deinterlacing and/or xvmc?

actually - all of a sudden I've got a interlacing problem (with or without the deinterlacing checkbox set).

xvmc - no
deinterlacing - yes, although I don't generally see much difference

ok just for the record, because some of the last posts make it sound like there is some confusion.
XvMC = no deinterlace no mater if the box is checked. postprocessing filters do not work if xvmc is turned on at all ever.
If XvMC is turned off you have the option of using the postprocessing filters or not. I know I can tell a large difference using the deinterlace filter when xvmc is off particularly at resolutions other than 640x480.

That's odd. I was under the impression that the new drivers supported XvMC with interlacing. I must be misinformed.

the new drivers support an interlacing output mode, that works with or without xvmc on, but the deinterlace filter will never run with hardware decoding, or any other filter for that matter, because it is hardware decoding.

Hi Everybody I just wanted to follow up with you all as I managed to get a sharp display, finally. Thanks for everyone's help. In the end, I picked up a $50 FX5200 card and reinstalled the new 6111 drivers - I also re-linked the library file as per tjc's instructions in this thread.
Out of the box, the 5200 with the new drivers looked better than my on board TV-out but it still wans't sharp. I ended up messing about with the nvidia-settings application which you have to run on the actual machine not on X (Thanks Xsecrets). On the TV-Out menu of the nvidia-settings app I noticed a few different options that weren't available for my onboard TV-out. In particular there was a Image Sharpening slide. Also there is a flicker control slide which on my system was cranked all the way up (this is significant).
So to increase the overall sharpness first I made sure that both the flicker control and the sharpening slides were all the way down. (You display may dance around a bit - mine did). Then you gradually increase the flicker control setting just until the display looks static - but not any further. I noticed that if the flicker control is too high it actually dulls the picture - so only apply as much as you need. That was my problem all along.
Once the flicker control is appropriately then THEN you can start to increase the sharpness using the Image Sharpening slide. Don't just crank this all the way - too much sharpening looks bad. You have to play around with things to find the right amount. With these controls you van actually sharped the image a little bit more than the broadcast but you have you really use a light touch. There is nothing worse that an oversharpened picture.
My display isn't perfect but I got rid of that annoying fog over everything. Now I need to just reposition the frame a bid and then I think I've got a little noise coming in on the capture side of things (PVR 250.....A nerd's work is never done. I'm wondering if there is a way to boost the signal before it goes into the capture card. I'm already using well shielded cables and I think that they are well isolated from power cords, halogen lamps, cordless phones etc....
I'm using a XF86Config-4 borrowed from tjc but I never got the HD480i working on my Analogue 27" Sony TV so I'm just using NTSC-M.....

I forgot to mention that I'm now running my LiveTV encoder at 640x480 with a really high bitrate (I need to ease it down once I figure out the noise problem). Also deinterlacing is out and there are no interlacing artifacts during motion, no motion blur.
Also XVMC is on. I don't really notice much difference but fast motion seems more fluid and the CNN ticker as well.

Could someone please advise with an idiot's quide as to how to install this new driver, or is it just install-nvidia.sh ???? And also how would you get into the new control panel program ???? Also the best settings for UK(PAL-I) for the XF86Config file
Sounds brilliant, I recently got a new small case which will fit into the tight gap on the tv stand, with a much better avermedia dvb card, and an XFX 128MB geforce 5500 with tv-out, loaded up myth, tv-out rubbish from base install of Knoppmyth, ran install-nvidia, which seemed to go through OK, but then X wouldnt start up at all.....
So i thought I would have to stick with my shuttle box stood to the side of the telly, £100 wasted on the new gear !!!!
If this drivers work well for tv-out, I will be well chuffed !!!! And then back to the age old problems of getting Mame and dvd's to work !!!!
Everyone keep up the brilliant Myth work, I love it !!!!
(Cesman, you still havent corrected the address for my UK mirror for Knoppmyth, it is http://www.a1ontheweb.co/uk/knoppmyth/)
