Here's my contribution...

I made a list of almost every tweak I have encountered, and came up with these registry key, which were copied and pasted from various sources, and I take no credit for them...sorry if there are any repeated registry tweaks...some of these tweaks may be old, but are listed for reference...note that these were based off the WM5 roms, and may still apply to WM6...make sure to make a backup of your registry before attempting to make any changes to your registry...

Increase camera frames per second

This tweak will let you increase the frames per second of the video camera to make more fluent movies:

HKey Local Machine\Software\HTC\Camera\ReParam\MP4Large (or Medium or Small).

Change the FrameRate value

the standard value is 10.. i have heard that above 19 it is laggy .. so i have it on 19 frames, and i think the high option for capture video can be unlocked in some kind of way in the registery.

Disable the MMS recording length limit

If you wish to record 'unlimited' video in MMS Video mode, adjust the following value:

HKLM\SOFTWARE\HTC\camera\AppDefSettings\P3\EnableLimit = 0 (DWORD decimal)

To re-enable the limit:

HKLM\SOFTWARE\HTC\camera\AppDefSettings\P3\EnableLimit = 1 (DWORD decimal)

Please note that most providers (sending an receiving) do not support MMS sizes greater than 100KB

Adjust the MMS recording length limit

If your provider (and the recipient) allow a larger MMS size, you can adjust the recording length in maximum filesize by adjusting:

HKLM\SOFTWARE\HTC\camera\AppDefSettings\P3\LimitSize = 80 (DWORD decimal)

The value '80' there is 80KiloByte.

Note that you can set this to any value you like, but your/the recipient's provider may not accept larger MMS filesizes

Adjust the Camera UI color

If you prefer a color other than the default bright green for the Camera text/icons, adjust:

HKLM\Software\HTC\Camera\Common\?FontColor = 00FF00 (DWORD hexadecimal)

The color is defined by 3 hexadecimal values stuck together - like HTML color codes:

Value: BBGGRR

Red: 0000FF

Green: 00FF00

Blue: FF0000

Adjust Self-timer countdown text color

If you prefer a color other than the default bright green for the self-timer countdown text, adjust:

HKLM\Software\HTC\Camera\Common\CountDowntColor = 00FF00 (DWORD hexadecimal)

The color is defined by 3 hexadecimal values stuck together - like HTML color codes:

Value: BBGGRR

Red: 0000FF

Green: 00FF00

Blue: FF0000

You need to create Registry value of name "Locale" and type of "String" and data of "Localization ID" within

[HKEY_CURRENT_USER\ControlPanel\Keybd]

Localization IDs:

French = 040c

German = 0407

Italian = 0410

Japanese = 0411

Kazakh = 043f

Russian = 0419

Other IDs can be found here: http://www.microsoft.com/globaldev/reference/winxp/xp-lcid.mspx.

Some versions of the OS seem to be case sensitive on this value, and if it does not work, try upper case letters.
