0BBC HD LogoUna solución temporal para el ATI / 7MC / Problemas BBC-HD

-actualización-
Este problema ya se ha solucionado mediante una actualización del controlador de ATI. Para más información ver el último artículo en el tema


There appears to be an incompatibility between the Microsoft codecs in Windows 7 and BBC-HD (and other broadcasters too I understand). This causes some image corruption on all platforms I have tested, but on ATI hardware it results in continuous corruption which renders BBC-HD unwatchable. For anyone looking for a solution to this problem keep an eye on the Microsoft knowledgebase article KB2008334. Mientras tanto, there is a work-around, as long as you have a sufficiently powerful CPUdisabling GPU accelerated H.264 decoding. To do this requires a registry edit

  • Ejecutar regedit
  • Vaya a HKEY_LOCAL_MACHINE SYSTEM CurrentControlSet Control Video
  • In video there will be several subkeys. One of these is for your graphics card. To locate it you will have to look through each in turneach will have a video folder inside it. los “Servicio” value inside the video key is the clue you needI have several that start RDP which is presumably related to remote desktop so they’re not right. I also have one which is called atikmdag. Este es el que!
  • When you’ve found the correct subkey of video expand the key 0000 (if you’ve got the wrong one you probably wont be able to expand 0000)
  • Expandir “UMD” y entonces “DXVA
  • Create a new string value called VForceUVDH264
  • establezca el valor en 0
  • Reiniciar. Prueba BBC-HD. You will get 5-10 seconds of initial corruption but playback should then become normal and should remain that way thereafter

This tweak will disable gpu acceleration of playback of all H.264 filesso if you have a blu-ray collection you’re going to be decoding with the CPUexpect much higher CPU uso. Any modern dual-core CPU should be plenty capable however.

Once Microsoft issue a fix for this problem simply go back into regedit and delete the key to restore normal functioning.
