I think I found a much better solution to fix the lag.

Remove /System/Library/Extensions/AppleUpstreamUserClient.kext

This kext is responsible for HDCP DRM crap, it is only present in 10.5.6 systems.
I tested in my system with 7.6 QTComponent and 10.5.6 NV drivers, no lag without this kext.
Please confirm.

It works for me. 10.5.6/8600gt

Thanks!

This does´nt work if you have two 7300 gs 512 mb cards in your hack I´m afraid, what you can do though is allways start new safari windows on the display connected to your first videocard then you can drag it to any display you want and it works like it should.

i can confirm this works perfectly with 7.6 QT and 10.5.6 NV drivers powering my 9800 GTX+. thanks very much, that was getting annoying.

[dparada78]

Works for me on my gigabyte ud3p, evga 8800gt! Just trashed the kext and restarted.

Chrysaor's fix worked for me too! Thank you very much!

Running Retail with a 9800GT enabled only through EFI String. Evga card.

WOOOHOHOOOO YESSSS Thank you man. After 4 days of searching i found a solution. Thank you so very much. MODS please make this a sticky!

[beboy]

Many thanks to Chrysaor for this solution ! =D

[EnzoFX]

Would it be necessary to restore this kext when updating?

[SoSa]

It seems to me mouse lag quicktime stuttering remained in 10.5.7.

Therefore Remove /System/Library/Extensions/AppleUpstreamUserClient.kext

[RepomanUK]

Just downloaded and installed the latest updates to Quicktime Player (v7.6.2) and iTunes (8.2) hoping they might play nicely with AppleUpstreamUserClient.kext and there is some improvement on my system - the jerkiness isn't anywhere near as bad as it was before.

But it is still there. Looks like time to reapply Disabler.kext
