Antigrunge, it took me about 20 minutes to recover from the laughter fit that your response caused.
Poet, don't take offense to the responses, no one is questioning your concern. But when describing facial contortions resulting in what sounds like a pig eating slop, it's hard to connect the dots as to how that sound coming out of your left channel would be properly diagnosed.
I would say, based on the age of that component, that it probably would not be cost effective to take it in to be checked, or even repaired. You have already eliminated the amps and the cables from the mix. So, it's most likely the DVD player. For a few hundred dollars above and beyond what it may likely cost to repair it, I might suggest looking at an Oppo BD 95 multi format player. I have one (no affiliation) It plays Blu ray DVD's, SACD, red book, etc. I use mine specifically for audio and I love it. The company has great customer service as well. That is my 2cents. Good luck
