Just bought a BD K980 Blu-Ray player with RCA connections to use with my old WEGA tv, but the digital audio won't work with any new DVDs, blu-ray or not. Called seller who said buy RCA with HDMI cable, then also bought an RCA to HDMI video (!!!) converter. Clearly I have no idea what I'm doing. Anything with digital 5.0 soundtracks can't be played properly, blu-ray or not. Any ideas on the correct hardware to buy and instructions for tech fools like me on how to connect it? Thank you!
