I am using RFID reader to detect the tags. Everything related to reader, mythtv and camera is already set up. All we need to do now is initiate the recording on some action. What is that ‘record now’ command that you are talking about. Where I can read about creating the lirc loop back?

I thought of doing the same (cat /dev/video0 > my.mpg), but the problem with that is we don’t want to get into the management of all the videos and then playing them back. So, that is why I thought of using the MythTV. I am currently using camera as a security camera which should record any authorized/unauthorized RFID tag.
Also, getting back to what you have suggested, is there any way so that I can playback the videos that I have recorded directly (from cat /dev/video0 >my.mpg) on MythTV? If that is not possible, is there any off-the-shelf video players which can play the RAW video format?
Also, what needs to be done if I wanted to store the prerecorded videos into the MythTV database, so that when I run MythTV it recognizes all those videos?
