When I extend the displays so they operate at their native resolutions there is bad stuttering on the projector. I have tried EVR Sync and honestly it isn't any better than EVR CP. I have no way to get the refresh rate to 24 Hz. I can force 50, 56, 59, 60, 70, 72, 73, 75 and 85 Hz via CCC. The regular options (ie not forced) are 50, 59, 60 Hz. How is this possible? Don't thousands of people all over the planet have multiple monitors? Do all of them have unwatchable video?

When you run in an extended monitor mode you must have AERO switched off when displaying on the secondary monitor (there is an option in MPC-HC called disable desktop compposition to do that).

As for the refresh rate, if you cannot get 24hz I would advise using 72hz (is a multiple of 24) and a tool called reclock (http://forum.slysoft.com/forumdisplay.php?f=85) but it can be tricky to set up. What you need to get is the reclock icon in the taskbar to go green, you change both the speed and slowdown media options in it to 5%. Enable the v-sync options in reclock also. This tool will speed up the media to match your refresh rate. Lasty use EVR-SYNC renderer (with reclock) with the option present at nearest v-sync.

If you do everything right you will get stutter free playback.

Tested some new ATI beta drivers:
http://forums.guru3d.com/showthread.php?t=319691
The drivers works for XP/Vista/W7 ,32&64bit. Also works for old AGP HD2xxx and 3xxx series.
Tested a video 720p H264,L@5.1 profile and 16ref.frames in MPC-HC. With internal MPC_HC DXVA decoder (compatibility mode=no check) the video plays with artifacts , less visible than with the previous ATI drivers. A slightly improvement though.
Nice AVIVO features with these drivers too.

Edit: Tested with Vista32bit and my old HD3650 based HTPC.

We know about these errors, we need someone to fix them

Cross-Mingw x86/x64 , with GCC 4.5.0 (Stable)

Just because a new GCC has been released doesn't suddenly mean it's the best option.

Agree.

But we need someone to test it and post the result here, otherwise the progress will be slow down a lot.

Hello people,

I've just installed Windows 7-64 bit, coming from XP SP3 32 bit. I´ve installed Win7 via dual-boot.

When i installed MPT-HT 1788 yesterday, it didnt work. It started up almost full-screen and without file-menu.

After a short while i figured out that i have to start the process in Vista SP1 compatibility mode. All works fine then.

Is this a known issue ?

Did you use a ini file or migrate your settings over from xp?

[tetsuo55]

I just installed the catalyst 10.5 and it's true, there is now support for above L4.1 files. Also some L4.1 files i had that showed corruption do not anymore.

But some of the files i tested still hang, so no more corruption but the video gets stuck while the audio continues, good chance that this is a bug in mpc-hc/ffdshow dxva code though

[clsid]

Perhaps it just ignores the level now and only looks at the other parameters like references frames?

@tetsuo55:
Are we talking about the same drivers?

Maybe you have a card with UVD2 or 2.2 . Mine is UVD+ and the changes are minor.

Edit: Does anyone tested the new ATI drivers with ffdshow H264 DXVA decoder?

[amango]

Yes! After disabling the DXVA-check within the MPC-videodecoder my Radeon 5450 card played some 1080P-MKV with 8 B-Frames without any errors! This also runs fine with the Catalyst 10.3 and 10.4 preview driver.

However I found out there are some video files with lower resolutions that does show artefacts while playing with DXVA, so the DXVA-check list needs to be updated.
Here is some info about files that shows artefacts on Radeon 4000/5000-cards. For this files DXVA should be disabled.

I don't think so. I have THAT specific behaviour with Cyberlink H264 decoder(DXVA)-PDVD9 in KMPlayer ,for some 720p H264 L@5.1 16 ref. files.

[Mercury_22]

After using load subtitles then save subtitles functions MPC-HC doesn't "see" the subtitles (the .srt file) saved in the same folder as the video unless I delete (or empty) the default.mpcpl file from the MPC-HC folder ( I'm using a ini file for settings) or I play other video with subtitles
If I open the default.mpcpl after trying to play the video for which I've used load then save subtitles functions I can see only the video file inside and NOT the srt file too or nothing (= the default behavior)

EDIT : Last working version I've tested is 1775 first not working is 1779 so my guess is that problem starts in rev

Revision 1778 - Directory Listing

Yep. Something is definitely broken w/ automatic subtitle loading.

Nope i didn't. It's a clean Win7-64bit install from DVD (firefox is the only other app ... that clean). I use BitDefenter internet security 2010, and are still working with a 1950XT and Catalyst 10.2. Also used the DX web installer to get DX up to spec, also all updates and patches from windows-update are applied (ofcourse with a legit windows )

I just grabbed the installer version of MPC-HT 1788 from xvid-video.ru and installed that on this clean system.

one point of interest maybe: Windows 7 insists on numbering my secondary-display, my TV, as "1" and my main screen as "2". Have no idea how to reverse that order, and why windows does that for that matter. Maybe Windows chooses the main display based on which has the highest resolution ?
Second point of interest: User account control [UAC] is switched. on. It protects by limiting reading from and writing to registry, am i right ? It does pop up when i dont start up in vista compatilbillity mode. Might that be what's preventing MPC-HT to start up reguarly ?

Fullscreen problem still exists in image below, where the image isn't 100% filling the screen, the taskbar can be seen.



For the evr-cp guys, can you notice any problem with the graph above. It was playing perfectly for a few minutes, then all of a sudden it moves like 3 frames every second. The above image is taken when it starts this. It has happened with all versions of nvidia drivers for the last few months, and only happens maybe once a week. Do any of the stats indicate what the stutter problem is caused by?

Another thing - What does the "Dynamic Range Control" checkbox do?

Compresses the audio's dynamic range. It is evil
