I have a coax cable coming straight out of the wall into a Sansui TV with an SDTV tuner. Channels available are both analog and digital. The TV also has video and audio input RCA jacks.
I would like to get a Digital Video Recorder that will work in this system.
I hope I'll be able to help you with this. You can get this All-In-1 Digital HDMI Componet HD Composite RCA DVR Recorder which is available in Amazon. I'm sure that this is compatible with your TV.
