Encoded video file downloaded from OnlineTvRecorder.com (OTR), a website used for recording and downloading TV shows; must be decoded with the OTRKEY Decoder program before it can be watched and can only be decoded by users with a valid OnlineTvRecorder account.
OTRKEY files are created when an OTR user chooses to record a TV program. The website then makes an OTRKEY file with the encoded video available for download, and the user can decode and watch it on the local computer. This method enforces that recorded shows can only be watched by users that record them.
NOTE: The OnlineTvRecorder.com website is localized in German.
