I have the same model and I also had that problem. It turned out to be the motor. Do you hear a faint humming sound? If this is similar, you will have to take it to a designated JVC repair shop.

If you have direct cable into the television, you will need to use an audio output if available on the back of your set into your HT system.

If you are using cable w/ a cable box you have two options. You can still connect everything directly into the TV then reroute the audio to the HT system... or, you could hook only video to the TV and audio from the cable box to the HT system. Really up to you.

how did you transfer the video from the card to your PC?

did you connect the camcorder to your PC or did you use a memory card reader?

if you can play the audio then what you need is the right video codec for the unit
try searching for video codecs through search engines

make sure that the software that you are using to play the video plays the file format of your video,

try using roxio, then connect the camcorder to your computer via USB, make sure that the drivers are installed, play the video through your camcorder then use roxio to capture it real time instead of the usual "copy-paste"
