Trying to get stutter-free 24p playback with ATI 5730

post #1 of 5
Thread Starter 
So I am using my laptop, equipped with a Mobility HD 5730 ATI card, as my Blu-ray player for my home theatre and am running Arcsoft Total Media Theatre 5. I run HDMI out from my laptop to my AVR and then hdmi to my LG PK550. I decode the audio on my PC and send a 7.1 LPCM signal to the AVR. Everything works great at 60FPS but as soon as I enable 24FPS in ATI control panel I get a stutter quite frequently on the video. I realize this is because the ATI card is actually outputting 24 frames and not 23.97 which is what is should be. I can select 23FPS in control panel but as soon as I save the changes it defaults back to 24.

I have looked into the Reclock software but that doesn't even work. I installed it and launched the config utility but there is no icon in the tray so I cant access the control panel or get it to do anything. I did set it up with Total Media Theatre as one of the associated programs, but when I launch that Reclock still doesn't show up.

Any solutions? It's ridiculous for people to spend thousands on home theatre PC's and multimedia notebooks and have to have so much trouble settings things up. I had a desktop HTPC before this and nothing ever worked properly without extensive research and trail/error. The PS3 seems to be the much better option at this point.

Thanks!

There's workarounds.

1. Go into the ATI control panel and set everything for 24p. Whether you choose 23Hz or 24Hz is immaterial, it'll default to 24Hz. SAVE the profile as something. It will save the profile in c:\\Users\\\\AppData\\Local\\ATI\\ACE\\Profiles as an XML file.

Go there and look for the following key:





The main thing in the key above (in bold) is the Refresh rate. Change that to 23 save the xml file and reboot. Perfect 23.97Hz.

2. You can apply this profile using CCC but make sure you don't change ANYTHING via CCC, otherwise it'll overwrite that change you made, and it'll revert back to 24.

You can use reclock with a VBS script to do the change automatically. It takes a bit to configure reclock and the script, and it depends on how good you are with this sorta stuff.

Your call

Thanks for the timely reply kapone,

I actually did go into appdata and try editing a profile with notepad last night, however I didn't do a system restart. I believe it was working but then I changed something else in CCC and things went back to normal. When you open up CCC AFTER saving the edited file, will it show 23Hz or 24Hz? The profile settings in CCC confuse me, they could have made it a bit more user friendly IMO.

And about Reclock...I just wanted to get it to work, like I said I can open the config file but there's never a system tray icon or anything under processes...I just need to figure out how to start the program! I am using Win7 64bit btw.

Thanks

I also had a few other questions;

- Everytime I close an application that was using audio (i.e. iTunes) I get a loud clipping sound coming from my speakers until I use another audio source. Why is this?

- I have heard the new mobile nVidia chipsets (435m for example) can bitstream hd audio, but can they also just passthrough pcm that has been decoded by the software player? I can't imagine no but just thought I'd get clarification.

Thanks
