I have a very old T.V that only has a coaxial input. I also have a Toshiba DVD player that only has composite video outputs. I have tried using both a vcr and an actual rf modulator to enable me to use this dvd player with my t.v. In both cases, the video is fine, but the sound is extremely low. If I turn the volume up on the t.v., I get hissing/crackling sounds so that the audio from the dvd is uninterpretable at any volume level. Does anyone know where I can get an old receiver with a coaxial output so that I can use this old t.v.?
