I Have A Lcd 32inch Tv And A Rca Dvd Sound System And I Need Major Help Getting Audio To Work For Everything!?

Magnavox 32MF337B 32-Inch LCD HDTV – tv description
RCA RTD217 5-Disc DVD/CD Home Theater System – dvd sound system
we have checked online and the manuals and even called magnavox ! We need help! Is there anyway to hook up the surround sound to the television with out the optical cables so that the sound works for tv channels(digital antenna not cable box or satelitte just directly connected with a coaxcable), our ps3 ( hooked up with hdmi cables), and the dvd player(hooked up through the avi1slot. The problem is that it works fine with the dvd player but how can we hook it up where we can get sound for everything? There is no optical cable spot on the dvd player but there is on the tv. It is the only audio out besides the normal avi1,2,3 and the 2 hdmi ports. You cant play the sound from the ps3 or the tv channels unless it is just through the tv since you have to switch the source to get to the audio on the dvd player surround sound. Any suggestions would help ! I really dont have the option of ugrading our surround sound we just bought this one and cant take it back very disappointed it didnt have the optical port on the back only the rca type connections.
