Q. please explain to me what exactly 6-channel direct mode is. i have the black 6 channel direct inputs on the back of my marantz reciever and 1 black ouput on my LG HDMI dvd upscaler labeled "Digital Audio". I recognized that all of these were black and was wondering what cable i would use and what sound it would deliver.
Answer
Normally you send digital 5.1 surround audio from a DVD or Blu-ray player to a receiver using a single digital audio channel. The digital audio could be sent between digital coaxial audio ports (RCA plug), digital optical audio ports (TOSLINK/SPDIF), or through HDMI ports which also carry digital video.
Your receiver has an option to receive 5.1 surround audio in an analog format (multi-channel direct inputs). The only time you would use this is if you could not connect your DVD player to the receiver with one of the digital audio connections described above.
You may also choose to use the direct inputs if you want to be able to hear master quality audio from a Blu-ray player. Lets say your receiver is older and can not decode master quality audio used on Blu-rays (Dolby TrueHD, DTS-MA, PCM Surround). Now its true that the Blu-ray player can send a backward compatible digital format that sounds similar to the audio used on DVDs. But if you connected the player to the receiver with the direct inputs, then the master quality audio could be heard instead, because the player is doing the decoding that the receiver can't do.
To connect to the multi-channel direct inputs, you need a DVD or Blu-ray player with multi-channel analog outputs. You can't connect a digital output to any of the analog direct inputs, they are not compatible and the noise created could damage your speakers.

Please Help Me Hook Up a Blu-Ray Player!?
Q. I have a 52" HD TV (1080p) and a JVC surround sound system that only plays regular DVDs. I want to buy a Blu-Ray player to put into this system. How do I hook it up? Please don't tell me I have to buy a new surround sound system to go with the new Blu-Ray player!
Answer
You may not need to replace your surround sound system! It depends upon the capability of your JVC system. Both the Sony BDP-S300 (does not support Blue Ray final standard profile) & Panasonic DMP-BD30K (supports Blue Ray final standard profile) support the output of 5.1 channel audio. If your JVC surround sound system can input these 6 signals (front L, front R, surround L, surround R, center & sub) you are in business. Other Blue Rays may support this as well; I am just not as familiar with them.
The Panasonic also outputs the audio via coax or optical cables. In any case, you would still use an HDMI or component video cable to your TV. On the Panasonic unit, you can configure this unit to disable the sound over the HDMI so your TV does not interfere with Blue Ray playback.
Additional Details: Just got home from work and verified that the Sony, Panasonic, Samsung & Sharp Blue Ray players all support 5.1 channel, coax and optical audio outputs.
