Thumbnail Generation for various Video files in Explorer

First of all, follow the previous blog and install the necessary codecs.
At this stage I'm assuming that you already have a directshow decoder capable of decoding the most common video formats. So lets go ahead with thumbnail generation

1. .avi Files
Thumbnails will be automatically generated once you install ffdshow or any directshow decoder capable of decoding these files. eg. xvid, divx

2. .mkv .mp4 files
While installing Haali Matroska Splitter remember to select .mp4 support,
Start->All Programs->Haali Media Splitter->Media Splitter Settings
Options ->Explorer Integration->Enable Thumbnail Extraction YES
Offset to a value between 8000 - 10000




Now add the following to your registry and restart the system. In order to do so, create a file named thumbnail.reg and paste the following into that file (Excluding BEGIN & END). Now double click the file to add these entries.

BEGIN
Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.mkv\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
@="{327669A0-59A7-4be9-B99E-1C9F3A57611A}"

[HKEY_CLASSES_ROOT\.mp4\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
@="{327669A0-59A7-4be9-B99E-1C9F3A57611A}"

END

3. .rmvb files
These thumbnails will be automatically generated upon installing Real Alternative Lite
