One of the neat features in hildon-desktop is that it can use PVR screenshots that can be loaded before an app starts, just to make it look like it started faster, unfortunately, most apps on Maemo 5 don't support this, a few stock ones (Clock/Settings/Modest), and very few community ones (fMMS, DrNokSNES, PSFreedom etc...) do.

This is a quick app that allows you to create PVR images, they will be saved in /home/user/.cache/launch/org.maemo.pvrcreator.pvr.
After an image is created, rename it to match the service name of the application you want to use it for from /usr/share/dbus-1/services/
Use this command:
to get a list of service names, rename the pvr file to the name you got from the command above, adding .pvr at the end.
Example:
Take a screenshot of the media player.
Trim the top title bar (including status menu etc...).
Place the edited screenshot somewhere on the device.
Use the application to create a pvr file.
Rename the file to com.nokia.mediaplayer.pvr



Thanks to thp, Jaffa, and frals, their source codes really helped in this app
