Re: Live TV

Just a Bug in the code for Live TV!!!

Not sure about that - I would expect more people to be reporting this as an issue. Look, it could be a bug in LiveTV that manifests only when a whole bunch of other conditions are met (codec, graphics card, DVB card, OS patches applied, etc etc).

I'm trying to work out what settings I can change in order to remove the problem, since not everyone, especially with similar setups, is working fine.

FYI, my video codec currently in nVidia PureVideo. It seems that if I configure my graphics card to 1280x768, 60Hz, then the PureVideo decoder no longer drops frames. And playback of non-LiveTV is also smooth with no tearing. LiveTV still tears.

Hi, I have the same problem :

MP : 0.1.3.0 no cvs
Codec : mpeg2dec included
Gfx Card Geforce Fx 5200 : 50Hz @ PAL Resolution, output via composite to the TV. MP is setted to use VMR9 renderless, fullscreen and exclusive directx mode :

LiveTV => Tearing
Timeshifted TV => No Tearing

I've been trying every single days cvs but unfortunately no luck and plagued by the "no signal" error as well. I'm also losing sync with the picture/audio when tv watching as well (Even timeshifted)

I'm building a couple of pc's for clients today both using 7800gt's so I popped one in to see if it made any difference vs my 6600gt unfortunately the same tearing until TS is enabled.

using 7800gt's...the same tearing until TS is enabled.

Good to know it's not my little FX5200! I was wondering whether a beefed gfx card was needed...

Maybe it's an NvidiaGfx+Live-PAL-TV issue???

I will shortly be doing a rebuild from an empty OS image, so I will let everyone know how it goes...

Re: Live TV

Yes ! Yes!!! Now it´s working!!!

Find the solution in the graphic settings.. Look for Game & 3D settings..

V-Sync is the problem!!

For Matrox card.. Flip pages during vertical blanking (v-Sync) Interval


Default value :Always . unless applications override.


Change this to : Always

My TV is now perfect!!!

Let me now if it solvd your problem!!!

I'm pretty sure I have V-Sync in my NVidia drivers set to On.
laeb66, maybe you can list any other settings (eg TV de-interlace, codec de-interlace, gfx refresh rate, etc) that you are using, since it may be v-sync in combination with something else that is the magical answer!

However, I did a re-install last night, from a clean OS image (MCE2005, actually - I'm always swinging back and forth between the two...).

This is now a clean MCE2005 install, all windows updates, with nvidia MCE 72.14 drivers, plus nvidia PureVideo codec, FusionHDTV v3.0.0.1, MP v0.1.3.0.

I have not implemented yet any of the other tips (eg PCI Latency, plus other WinXP updates suggested by Frodo).

I still get tearing in live TV, but on this install I haven't updated the graphics driver to set V-Sync to ON. So, I will do that as first priority tonight when home, and report back.

Live TV working fine now

The only thing a have done with PCI Latency is made from Bios set up..

Default value : Auto.

The new value: 66.00/33.00 MHz

Used codec: Dscaler MMX mode.

Looking fine with NVIDIA ( from Theatretek )
Same thing with Cyberlink..

Before a solvd this problem I put on both Video and Audio Delay for 10 ms.
This make some improvment.

Looks like MP Live-TV override V-Sync..
I gone test a Nvidia card tomorrow and se if I can find a way to lock the V-Sync.
Must be some more settings then ON or OFF.
For Matroxs it 3 way to set this. And all off them under Game & 3D

Hope this is to some help
