Lool thanks unfortunately thanks to my rotten cable tv provider i cannot fully enjoy tv captures, but that's offtopic here so nevermind :) But at least the dropped frames issue is solved for now.

This has been a great thread! Great detective work!
Just to add my 2¢... you are not alone in your Kaspersky issues. I was getting 3, 4, 5 BSODs per day back in June, and dumping Kaspersky solved about half of them. The new av/as from MS (Microsoft Security Essentials) works good with Win 7... give it a try. You won't even notice its there... the best thing you can say about an av/as utility.
ok thanks i will try it later.
Jeez both the "none (buffered)" and "full" methods are VERY good indeed... last nigh i did a NINE hour capture (yes you all read correctly!!) with ZERO dropped frames! And i also tested while doing several things on the pc and EVEN opening and closing the dvd tray which ALWAYS used to trigger dropped frames, but now none got dropped and no, there wasn't any problem in the capture file at all! Yeah i am sure happy with this now it's even better than in windows xp, finally.
Very interesting investigation!
However, sorting the DPC CPU usage summary table (from the Xperf trace) by modules rather than by functions would have shown directly that kl1.sys was the culprit without having to create a minidump and load it in windbg to find this same module from the function's address..

Excuse me from reviving this old thread, but I've been having the same "midnight freeze" issue for a year now, since I have Vista Business 64 bit (currently at SP2). I've decided to Google it once more after getting a freeze while playing at 00:00 today and found your discussion.
I have KAV11 (11.0.1.400), not KIS. I see it has been found Kaspersky, more specifically kl1.sys, is the culprit, nice work! Why is it doing this all the time at midnight though? Is there somewhere in Kaspersky's options we could perhaps change to stop this from happening? Some automatic, predetermined task we could disable?
Thanks
Well unfortunately i don't know how to help you because quite honestly i STILL have the same problem even now in windows 7 32bits and having a quad core amd 955 be cpu and KIS 2010, and i learned to "live with that freeze" mostly because i don't do anymore cpu based tv capturing and it's all using a hardware encoder tv capture card so i haven't worried about this problem anymore, and i am glad about that because i haven't found a way to fix this at all.
By the way the only reason i don't use KIS 2011 at all is because many times i get 100% cpu (in fact 25% of it since i have now a quad core) usage and i don't have that problem in kis 2010, but the freezes at midnight still happen unfortunately.
