I have an ASRock ION330 (OpenELEC RC7) to a H/K AVR to a Sony SXRD.
My problem is that my TV CANNOT do 24p, only 50Hz & 60Hz. My AVR can do 24p however. So I have been trying to get all 24p material to run @ 60Hz. I have edited my advancedsettings.xml like so, but XBMC will still not force 24p > 60Hz (and be able to switch to 50hz for 25fps material) regardless of what I have set "adjust display refresh to match video" and/or "sync playback to display" to. What else can I try? And for the record I am a big noob, so I would need a little more detail than most.

I was following the instructions in the first post, but I quickly discovered that X is not writing anything to XOrg.0.log. Any idea why that might be and how I might go about getting it to output something?
I was wondering if it was a permission issue - with the user who calls X not have write permission. I did a chmod 777 but that didn't solve it. Any ideas on why would be much appreciated. |

Okay, not sure what's going on here. I ran the script and everything seemed to go okay, but for some reason, I just can't get my GPU to output anything other than 60Hz. It's an nVidia GF9300 integrated chipset.
Code: xbmc@XBMC:~$ for i in 24 60; do xrandr -r $i; nvidia-settings -q RefreshRate | grep -o "[0-9][0-9].*Hz"; doneCode: xbmc@XBMC:~$ nvidia-settings -q "refreshrate" Code: xbmc@XBMC:~$ cat modes.txtCode: xbmc@XBMC:~$ cat /etc/X11/xorg.confI'm not sure what I'm doing wrong here. Edit: Just checked the manual for my TV (LG 47LE5400 120Hz) and found the following: Code: 1920x1080pQuote:24p Real Cinema (5:5/2:2 Pulldown)That suggests that it should support 24p material just fine.

I'm not sure if I found something or not, but here goes. Upon looking at /var/log/Xorg.0.log I noticed the following:
Code: [ 17.055] (--) NVIDIA(0): Detailed Timings:So it looks like X is seeing 24p, 30p, and 60p as valid modes, but, it looks like, from the last portion of the log, it's not using 1920x1080_24 as an option. I'm not quite sure if this means what I think it does or not, although I'm still not getting 24p output to my television. |

Okay, not sure what was wrong, but I ran the script again, and everything's working as it should this time.....odd.

Ok, so I don't know if this is an issue or not;
I have a Sony X series TV - a few years old now, but in any case it does support 24p beautifully. I've had Win 7 and XBMC running on it well - but recently moved to OpenElec via an ION2 box. Anyway. It's hooked up via HDMI to an Onkyo 607 - and then to the TV. I've added the modes manually as suggested by the OP. XBMC runs well. Movies and TV look sweet. No tearing. BUT Bluray rips flick to 24p. When I go back to the menu, the TV goes back to 1080. If I watch an SD tv episode, TV flips back to 24p. If I watch a high res tv episode, TV flips back to 24p. So it would appear that all of my content now wants to run at 24p. It looks good, but is this right? My modes are; Modes "1920x1080_60_0" "1920x1080_24" "1280x720_60_0" Is this normal? Should XBMC really be thinking 24p is the best playback resolution in all cases? Oh - this is on the latest pre-eden OpenElec build. |

Tv Shows are mostly 24p as well. I would hazard a guess and say that you have your XBMC menu set at 60Hz, if so this is why you get the "flicking" from the menu to BD rip/tv and vice versa. Basically the TV is adjusting it's refresh rate. On a PC you can check the fps of any video with a program called Media Info |

I've used this script countless times on Lucid\Karmic, I've got 10.10 Maverick x64 minimal, then unstable 01\11\11 build installed and this happens when doing the "automatic" steps in the OP
Quote:rob@XBMC-Bedroom:~$ 1/6 Backing up settings Any ideas? Thanks edit - this was under my account, tried logging in to the XBMC created account and it seems to work still get the bolded error, can't quite remember if that is normal though, it may well be?
