Optical Port 2

I don't quite understand what you mean with "the other plug", but if you connect your external DVD writer to any USB port, the computer must recognize it and for Windows there is no need to install driver for optical drives.

Probably if you don't want to be left with no free USB ports, you can purchase a USB hub, preferable if you invest in one with external power source like this one: USB 2 0 HUB Powered 7 Port High Speed free AC Adapter

Hope it helps!

Check audio cables. Switch cables to different port. If using optic cable be sure plug is seated into receptacle and cable is not linked or sharply bent. May have to check owners manual to re- program port that is being used.

You need to select the digital input after you connect an input source.

Optical signal strength is sensitive to small-radius bends in the cable.

DON'T LOOK DIRECTLY INTO AN OPTICAL CABLE or PORT.

Optical digital cables can't be magically wired to copper inputs. NO digital signal can be magically connected to an analog interface and work.

Even if you could do what you propose, how would you control volume?

Why don't you just connect the BluRay to the JVC system and let IT handle the audio to the sub and satellites?

Run an optical cable to the JVC TH-C60's Optical In port. Make sure there are no tight bends in the optical cable as that will degrade its ability to transmit a signal.

Ive had the same problem with mine. I have a universal remote and a blu ray player separately installed on my tv. The only way i was able to play the ps3 without calling geek squad to reconfigure my tv was to unplug the blu ray and put the ps3 in its spot and push watch bluray. It worked great.

On the Sony The HDMI takes "priority" over all others, that's why you loose audio. If you run your DVI/HDMI to the TV and optical to the soundbar that would fix your issue. If your TV does not have Multiple HDMI inputs, you can get a DVI/Component adapter for your MBP then run it to the TV, or, If you have to have HDMI just to have HDMI, you can get a 2:1 HDMI switch and still have optical to your soundbar. Make sense? If youneed more help, just post a comment and I'll help some more.

Steps to hook up DVD player:

1. Plug in DVD player
2. Plug in VIDEO cable to back of DVD player
There are multiple video out cable options: HDMI, VGA, RCA
If you aren't sure, use RCA (red, white, yellow tri-plug cable) and plug yellow into VIDEO OUT port.
3. Plug other end of video cable into TV's VIDEO IN port.
4. Turn on TV to the INPUT channel that corresponds with the input port you plugged the video cable into. Usually, this is either VIDEO1, VIDEO2, INPUT1, INPUT2, or channel 3.

I had the same problem with my PS3. I have a HD cable box with HDMI out, a Sony DVD player with HDMI out. The Sony receiver STR-DG800 only has the HDMI inputs (sat/tv and dvd) and the HDMI is only a pass through port and will not decode audio.
I purchase a HDMI 4 port switch from Newegg (HS-41A0 http://www.newegg.com/Product/Product.aspx?Item=N82E16812168003&Tpk=HS-41A0) to hook up the DVD and PS3 to the DVD HDMI and switch between the DVD player and the PS3. It took me several days to figure out how to make this work with the settings on the reciver.

1 the DVD player must use the coaxial in jack for sound on the receiver.
2. the PS3 must use the optical connection on video1
3. the sound settings in the PS3 must be set to PCM
4. set the sound setting on the receiver to the following

a. on the remote press AMP button then the MENU button, next press the down arrow to you see 5- AUDIO SET - then press enter.
b.set sound decode priorty to PCM
c. next scroll down to you see digital assign - press enter
assign VID1 OPTICAL to DVD ( this allows the pcm output from the PS3 to play through the receiver), next assign DVD to COAXIAL setting DVD to DVD (this allows the digital sound to play from your DVD player).

So when you use your remote and select DVD, you can use your PS3 or DVD through the 1 DVD HDMI port.

What port do you have the HDMI from you BD player into on the 510. If you have it on the DVD port then fiber optic will do you no good, the DVD HDMI only supports digital coax, the Video2 HDMI only accepts fiber optic, and there is an extra fiber optic for the Sat input. If your BD player does not have digital coax out, or if you dont want to buy another cable, just move the HDMI from DVD to Video2 on the 510. I am willing to bet you have the BD player plugged into the DVD HDMI port and the fiber optic cable from you BD player to the Video2 fiber input.
