I did some searches and couldn't find much info on this subject. I assume this setting is for reverse telecine but am not sure if I should enable it or leave it off and let my TV (Samsung PN64D8000) handle the duty by sending it an 1080i signal to engage Film Mode. Other than that I have "Use Video Player Settings" selected vs "Use AMD Settings" under "Basic Video Color". I'm using the "Vector Adaptive" Deinterlacing Mode and have no other video options checked including "Enable Acceleration". Under the "Gaming Options" I have left all settings on default (3D Settings, Anti-Aliasing, Anti-Aliasing Method, Anisotropic Filtering) Any suggestions are greatly appreciated, thanks!

Thanks for your suggestion Andy! So the graphics card should definitely do a better job with reverse telecine?

Very basic settings (in CCC 13.4) are:

Color:
Basic Video Color: Select "Use Video Player Settings"
Advanced Video Color: Uncheck all (you may need to check "Dynamic Range" to get proper black and while levels in PowerDVD etc.)

Qualtiy:
Deinterlacing: Check both.
Uncheck all the others.

Without "Pulldown Detection", a telecined content may be treated as an interlaced content, hence you may see wrong effects.

Thanks for chiming in renethx! When you say "check both" for deinterlacing do you mean to check automatic deinterlacing and 4:3 pulldown? Thanks again!

I was under the impression that I could have the TV handle the pulldown detection by leaving it off on the computer and sending it an interlaced signal thus engaging the film mode. The question then was if the TV or graphics card would do a better job with the process. Of course I should test and see what looks better to me but I'm always curious to get the general consensus. Sorry I missed this part of your post previously!

Yes, you can send interlaced signals and leave deiterlacing / IVTC to TV by setting the desktop refresh rate to "29Hz".

Thanks again renethx! It ends up that having the TV handle the pulldown with my set up produces much better results. When enabled on the graphic card SD content suffers from a lot of jaggies. I should have simply compared the two to start out with (doh!) I just assumed the difference would be much more subtle to the point I would just feel better thinking I made the selection that was supposed to be best, ha! Thanks again!

Just noticed this thread. I have used amd in my set up over the past 4yrs and 4 generations of amd video cards, latest sapphire hd7950 OC 950hz version. I use PDVD12ultra sometimes and have used their products since version 6. but ,i tend to lean more to the freeware MPC BE and MadVr combo. I have a LCD 42" with that tru motion 120hz marketing technique. I also watch Netflix streaming and some you-tube as well.
I have not really noticed too much differences checking or unchecking that pull down box. am on catalyst 14.4 whql now and usually am at the newest beta on one computer and the latest stable release whql version in the other the other one has an asus 5870 v2 still and is working fine for what i do, am still using a4870 in a third which is fine for movies and videos too
but that pesky pull down box has kept me switching for years. I do see some more smooth clean streaming via netflix Acorn british tv rerun videos with the pull-down checked and the automatic interlacing though the tv also has that capacity and i check the 'gpu' to do the scaling in that tab and way down in the video global i check both boxes for keeping settings as well as smooth motion.
there have become so many overlapping feature options among all the different video renderers and players there can be 'interlacing' automatic options in all of them and each has separate triggers to turn it on and off and do slightly different things and/or in different ways. same with the slow motion options.
It can be a very confusing area and only way i have figured out what to do is trial and error. since pull-down detection may do something on one movie and not anything at all on another. i have spent half a movie testing and changing and missed the entertainment value completely (of the movie) and given myself more of an on the job training opportunity and whatever combo i found to work best, was not good for the next video i wanted to watch.

LG42LD550, ONKYO TX SR608, POLK M70s 7.1POLK 10"SUB, LG BD570, PINNACLE USB PVR-HD. GA990FXA UD3, SAPPHIRE HD 7950 OC 3Gb GDDR5, AMD FX-8150BE@4.0, 16Gb GSKILL DDR3 1600, SSD: CRUCIAL M4 128Gb, HDD: 3- 1TB SPINPOINT F3, WD4GB MY BOOK DUO LAN CLOUD , CISCO E3200, TP LINK 8PORT SWITCH; CISCO DOCS3.0

I find AMDs telecine detection to be extremely poor. It never gets the telecined videos I have correct and just deinterlaces them when it isn't needed. madVR film mode overcomes this though.
