Since I didn't start the original thread, please lets continue the discussion here, and i will try to keep the first post updated.

Update: The team decided to update the version, to provide the best evr experience we can with the 0.2.3 release. Note that this feature is still experimental though.

If you are new to the discussion, you might want to check the original thread.

A few things to note:

*) EVR will work in XP and Vista, but you will only get HW-acceleration under Vista.
*) Exclusive mode is not supported, but AERO does get rid of tearing, so it is preferrable to enable it.
*) you can get the same HW acceleration when using VMR9 + XP
*) The main reason to use EVR+Vista is better picture quality (in theory, but many users are confirming this)
*) check the homepage of your card vendor to see which features your card supports. nvidia's lists can be found here
*) for reporting bugs, please attach the log from MP Test Tool, or at least Mediaportal.log and vmr9.log

Changelog:
07-11-06: (version is in SVN builds >= 16476)
*) fixed a random crash
*) added workaround for ill-behaving DVD FastForward/Rewind

Eabin hope you do not mind this.

Extract "dshowhelper.dll" to your Mediaportal folder (default c:\programfiles\teammediaportal\mediaportal)
and then start MP configuration, under "Directshow Filter Control" expand and choose EVR, select use by ticking box.

Exit MP config with the ok button.

Enjoy

Oh finally I understand why my EVR support doesn't change nothing: I was missing the updated DLL.

Thanks for starting a new thread Eabin.

Is there really no way to fix the tearing without enabling aero? I've tried the updated .dll.

On my HTPC:
C2D 2.0ghz
Geforce 7100gs (obviously the bottleneck)
1920x1080p

If EVR + Aero Enabled = Looks beautiful, but video is slightly too slow. A delay builds up slowly over time, about 1ms per second. I think its related to my video card, but I'm not 100% sure - overclocking the video card seems to have no effect. But this only happens in 1080p - at 720p, or even 1440x1080, there is no delay.

If EVR + No Aero = Colors look good, video doesnt lag, but there's tearing.

If EVR Off, VMR9 mode = Video is washed out.

MPC has an option for EVR called "Direct3D Fullscreen (remove tearing)". Using this option forces the video to be fullscreen, but there is neither tearing nor delay.

EVR seems to be completely independent of Aero, and enabling Aero on a marginal video card such as the 7100gs seems to push it over the edge. There has to be a simpler way of getting tear-free EVR video without Aero on, which is really of no use to a fullscreen mediaportal HTPC.

And why would VMR9 video be washed out compared to EVR anyway?

Eabin,

BTW, can you also take a look at TvCardAnalogBase.cs and elevate the VBR for Hauppauge cards so that quality in TV£ will be as good as in TV2 ? Here a reference post: http://forum.team-mediaportal.com/sh...2&postcount=11

Thanks in advance for your work.

Hi Simone,

Sorry for the bad news, but I will revert any change to the quality control in tv3. It gives poor results for some users. I have a sample mpeg if you don't believe me. We can't introduce an option that will make tv unwatchable for a large portion of the user base. I'll take a look as to what the max value I can make it without affecting everyone.

[bd2003]

One more thing I noticed:

With EVR + Aero on in MPC - having the option "lock back buffer" unchecked = no tearing, but lag. The video looks and plays identically to MP, so I assume the same settings are under use.

With EVR + Aero on in MPC - having the option "lock back buffer" checked = no tearing, no lag.

Sounds like a bug or something isnt implemented properly perhaps?

Hi diehard2,

what are the changes you nee to revert from TV3? Can you send me the test MPEG to verify I'm on the same situation as others ?

Thanks in advance for your work.

MPC = MP ?

[Eabin]

nope, MPC = MediaPlayer Classic. There is a modded version by casimir666 which adds EVR support.

Hi Simone, I was saying that I can't make any changes to that section because it would impact too many people. I'll look at bumping up the quality a little bit, and i'll let you know. I'll post the mpeg soon.

Hey Eabin,

I believe you can add the same options (at least the filtering ones) that I've added for the VMR9. So, that's my small feature request.
