.mkv large file choppy playback issues on Windows 7 - fast/slow playback
I've been trying to identify this problem all day with no luck.
I'm having problems with playback of large .mkv (x264) files, files above 4 GB as strange as it may sound. When I try to play big .mkv file above 4 GB it starts fine, audio continues, than video slows for a moment and after that tries to compensate, then slows again. That's all I've got with big files. Issue is random, somewhere video/audio playback is OK, than suddenly starts with above symptoms.
When I watch 1-2 GB files with the same encoding I have absolutely no problems?! I even tried 1080p files ... same story. This seems to be somehow decoder related.
I'm using clean install of Window 7 Enterprise x64, and I've only installed AC3 Filter 1.63 beta and the latest version of DivX 7 (registered).
I've tried both Windows Media Player 12, and Media Player Classic, both behave the same.
I can eliminate this problem by using third party codecs, but the problem is I only want to use DivX 7 it has everything I need for video playback, I don't want milions of codes that spoil the system.
System is Core i7 920/12 GB DDR3 RAM/2x500 GB RAID0/Creative X-Fi/ATI HD 4890 1GB
