Windows Explorer crashes in Large Icons (thumbnails) view

[dazed_00]

Whenever I view a folder which contains .MP4 (H264) video files in large icon view (shows thumbnails), Windows 7's Explorer crashes. Explorer loads for a few seconds, the green progress bar shows up, and then boom!, Explorer crashes. The thumbnails are not shown before crashing. Does anyone know how to fix this?

I tried setting Folder options to 'Always show icons, never thumbnails' (disables thumbnails) on the same folder with MP4 (H264) video files and Explorer doesn't crash if the MP4 thumbnails aren't shown. I tried testing in other folders containing other video formats (with 'Always show icons, never thumbnails' set to off) like .AVI/Xvid, without an MP4/H264 file, and Windows Explorer shows the thumbnails fine without crashing.

I have not currently experienced problems with other formats, only MP4/H264. The only media players that I have installed are KMPlayer and VLC Media Player which both do not install external codecs, AFAIK. The only external codec I have installed is CoreAVC, but I have been using CoreAVC for months (KMPlayer+CoreAVC is one of the first things I installed in Windows 7) without any problems (this issue just arose a few days ago).

I am using Windows 7 Ultimate, 32 bit.

Note: I prefer a solution that will not end up disabling video thumbnails for MP4 files. I still would like to see MP4 video thumbnails, if possible. If the video files themselves are problematic, I reckon Explorer should not crash and just not show the thumbnails.

Whenever I have encountered a similar problem in the past, one of the files in the directory is corrupt, and Explorer chokes on it. Create a test directory that shows the thumbnails. Copy the files into it one (or a few) at a time, until you get to the one that kills Explorer.

I have experienced crashes with .MKV (H264) video files too.

I checked out my Media player and Codec installation settings and it appears to be, as of this moment, caused by Haali Media Splitter (which is an optional installation component, that is checked by default, with CoreAVC's installer). I've uninstalled Haali Media Splitter and I now experience no crashes with MP4 or MKV video thumbnails, so far.

I guess the next questions should be: what does Haali Media Splitter do? What might have caused it to crash Explorer (I have it installed for months along with CoreAVC)? And is it needed for watching H264 (MP4/MKV videos) in KMPlayer (which I configured to use CoreAVC)?

I will post here if there are any updates in case someone else also has the same problem.

^+1 same thing happened to me with video files (.mkv h.264), luckily I knew which file it was and went to it via command like and deleted it.
