Sony RDRVX515 DVD Recorder
Echo Chamber
We bought this model for the ease of dubbing VHS tapes to DVD. Dubbing was very intuitive.  Despite some other reviews that said the color was washed-out, we didn't have any problems with color issues.  However, the audio function was terrible.  While playing DVDs (which is most of the mileage we would put on the machine) the audio sounded hollow and tinny -- like an echo chamber.  Neither my wife or I are audiophiles -- this just sounded bad.  We tweaked every setting, and triple-checked  all the connections, but nothing helped.  Finally, we just hooked our old player back up and the sound was fine.  Ultimately, we returned the unit.
