Actually.. I believe the most accurate one is
Code:
74.176 1920 2558 2602 2750 1080 1084 1089 1125
The default one from my Onkyo's EDID results in 74.16/(2750*1125)*1000000 = 23.9709090909
i.e. <mode id="0x1ed" name="1920x1080" w="1920" h="1080" hz="23.97091" current="false" preferred="false"/>
-->1 frame skip every 195 seconds
FernetMenta's results in 74.175/(2750*1125)*1000000 = 23.97576
i.e. <mode id="0x1e8" name="1920x1080" w="1920" h="1080" hz="23.97576" current="false" preferred="false"/>
--> 1 frame dupe every hour
Yours results in 74.23/(2752*1125)*1000000 = 23.9760981912
i.e. <mode id="0x1ea" name="1920x1080" w="1920" h="1080" hz="23.97610" current="false" preferred="false"/>
--> 1 frame dupe every 3.75 hour
Mine results in 74.176/(2750*1125)*1000000 = 23.976080808
i.e. <mode id="0x1e8" name="1920x1080" w="1920" h="1080" hz="23.97608" current="false" preferred="false"/>
--> 1 frame dupe every 5 hour
Note that the actual preferred value is 24/1.001 = 23.976023976, not 23.9760000.
And since the precision of the pixel clock seems to be 3 digits, 23.97608 seems to be as precise as one can get. Adjusting the pixel clock to 74.1758 doesn't seem to have any effect, at least according to xbmc-xrandr.
Granted, all alternatives except the 23.971 one are acceptable.

It's more accurate than EIA-CEA one (74.175 pc) and most accurate working 23.976 modeline I've found, also it works better for me on some displays.. No more missed frames and 24p perfectly fluid. If you're happy with the standard one (23.97576) you don't need to change it, otherwise it's definitely worth a try.

OK wait....should we use this modeline or the other one this is closer to 23.976 also will this flux my out of sync issues with some 23.976 material? I'm using recent GIT

I would rather use the EIA-CEA standard which is the one I have posted. See Table 4: http://read.pudn.com/downloads122/ebook/...-861-B.pdf It has a pixel clock of 74.175
a/v sync is a different story.
