Sorry, just saw this thread.
I purchased the 32" Regza with the built-in DVD player about 2 weeks ago, and I've been quite happy with it. I'm not a videophile, but have been impressed with the HD picture on it, as well as the picture from the DVDs. My HD comes via the QAM tuner as opposed to "true" HD cable or an antenna. This is also a nice feature of the TV, as not all of them have the QAM tuners.
The SD picture is pretty good as well. Not as good as on my SD TV downstairs, I don't think, but quite respectable.
I've used it primarily for sports and news, and I haven't noticed significant ghosting or other issues related to poor pixel refresh rates. The contrast is quite good, so you get nice blacks.
The sounds quality is fine, but this isn't my primary TV so that wasn't a big consideration. Unfortunately, I won't be able to test it out until I get back home tomorrow night, so I can't get you a better answer.
I looked at several others, and although I also liked the 32" Samsung, this one filled everything that I was looking for, including the built-in DVD, which we liked because we're going to mount it.
Also, the remote and setup are fairly intuitive, which is a nice plus, and it's a fine looking piece of equipment. You have to attach the stand to the TV if you don't mount it right away, but that took a grand total of about 5 minutes, so no big deal.
Let me know if there's something specific you'd like me to check out for you.
