Panasonic DVD-LS50 7-Inch Portable DVD Player
Adding another H03 victim to the list.
We researched portable DVD players extensively when we bought this one (Nov. 2004) and we decided this one was worth the cost.  We certainly believed it would last longer than it did.  We just got hit with the H03 error as well, and in looking at the other previously written reviews, we see that Panasonic is not standing behind this product.  Stating the obvious, Panasonic has lost our business.  We're writing this review to add our one-star rating to the list.
