mp4 files crash with Avast 8

Avast Free Antivirus / Premium Security
1

Just put in Avast 8.0.1482.

Now all mp4 files crash.

They crash on YouTube, and wherever else I find them, and they crash in whatever I try to play them with.

It goes blue and everything is frozen and I have to knock out the program with Process Explorer.

How can I fix this?

Windows XP: Click Start> Control Panel> Programs> avast> Repair

Windows Vista / Windows 7: Click Start> Control Panel> Programs> Programs and Features> avast> Repair

Thanks for the quick reply!

But that didn’t do it.

Now the screen is green and the audio plays but there’s no image. I click it and it tells me ‘The program is not responding. If you wait it may respond again.’

use the uninstall tool
Safe Mode

a new installation

Solved!

Alas!

It’s not solved.

After uninstalling the old and reinstalling the new it worked, but today it’s back to not working.

Blank screens, audio only.

Hi all,

As a side note, YouTube converts uploaded videos to flv, not mp4.

flv files play without a hitch.

This does not play,

As annoying as that clip was it does work fine here on all three systems running avast 8.

I should mention,

DVDs won’t play either.

When I try to play a movie it says,

“Windows Media Player cannot play this DVD because there is a problem with digital copy protection between your DVD drive, decoder, and video card. Try installing an updated driver for your video card.”

I did that. Still won’t play. Same message.

Windows media player might be detecting the copy protection because maybe you are trying to play a copied disc ? is your player set to the correct region ?

It’s a disk I got from Blockbuster.

My solution was,

I uninstalled Avast and put in Kaspersky. Now everything works.

I have the same problem. Not just mp4 videos, I have problem with other video formats as well. I’ve uninstalled and did a clear install. It worked first time but after I restarted my PC problem came again. I cannot watch films at my PC while avast! is installed. Whenever I try to watch film I have a green screen. I love avast! and I don’t want to use any other free anti-viruses. Please solve that problem as soon as possible. Sorry for my bad English by the way.
