Ok, I have an old JVC XV-511 DVD player that works really fine (until now?). I recently burnt a VCD and was able to watch it. Now that I try to watch some legit DVDs, there's simply no audio anymore. None of my regular DVDs play audio anymore. But if I put back that VCD, audio plays fine!!! What is happening with this? Is my player all messed up or what? I tried everything I could imagine, including unplugging and replugging several times... Anyone knows what's going on? thanks... .fs.
