Excerpt: The sony bdp s300 dvd blu ray player is a 1080p with dvd upscalling via hdmi. I still have an extensive dvd collection that I use my old dvds for but of course have been switching over to blu ray :). Its pretty easy to use I use the remote , which by the way I wish was backlit but its not too big a deal, seamlessly with the functions. Picture and sound quality are great. They have played every disc I put in them.
Excerpt: We purchased this Sony BDP-S301(Sam's Club version of the BDP-S300, only difference being the S301 included an HDMI cable) Blu-Ray player fairly early on along with a 40" Sony flat panel HDTV, so as a result, while it has been a very reliable and solid piece of equipment, it does take about a minute to power on and load Blu-ray discs. I think this has improved somewhat with firmware upgrades.
Pros: Fantastic picture! I bought mine 2 years ago for $250 (aafes.com), when all other blu rays were costing almost twice that price.
Cons: No ethernet plug in. Sony will send you the update "via the mail". I've already updated mine to "4.40". I have a plasma tv which works best in darker rooms. I only wish sony had backlit the remote.
Summary: I guess I am lucky, mine has worked fine. I also got lucky on the price, I bought it here on 2/17 for $350 with free shipping, $70 less than the price today. Not sure I'd pay $420 for it. I have tried about 20 movies, BD and DVD. It has player all but one (a DVD - Clay Pigeons) without problems. It is slow to power up and some BDs take a while to load. BDs look great on my 50" 720p Panasonic. The best feature is the up-converting, normal DVDs look great.
Summary: Very happy with it. Makes my 52" Aquos LCD look awesome. VERY slow loading times though. Perhaps this will improve with time. Haven't compared to any other units though. All in all a good unit other than slow boot up and play times. **Update** Player stopped working after an update in April of 2010. Even though it was out of warranty, I was able to convince Sony to look at it since it happened right after an update.
