Are you still just using it for stereo playback? If so, then it it may be worth having it repaired. If you're only listening in stereo, I'm not sure there's really any reason for the lossless codecs. But that said, the BD player would do the decoding and you send that signal to either the stereo analog inputs or multi-channel inputs, which the 3803 has. To make use of the MC inputs, you need to make sure you purchase a BD player with the MC outputs.
