I found this forum and just thought I'd chip in with my initial impressions after owning a BD690 for a couple of days.
Disclaimer: I have not gone through the manual yet. I've just been trying stuff out by using it.
I came to the BD690 from owning a BD390 previously. Actually, I still have the BD390 but it has now refused to recognize any type of disc at all, even cleaning discs, after almost exactly two years of ownership. It is out of warranty and would have cost as much or more for LG to repair it than for me to just buy a new unit. So, I decided to "upgrade." I admittedly did so after a minimal amount of research, but thought the BD690 looked nice on paper.
Well...it's definitely a mixed bag. So mixed, in fact, that I'm not sure yet if I want to just send the thing back and start researching other units.
The good:
1. It starts up and gets to the main screen WAY faster than my BD390 did.
2. The Netflix app is cooler, since it now lets me search for and add instant-play titles from my sofa, rather than having to queue stuff up from my PC first.
3. It has a ton more apps than just the core Netflix, Vudu, YouTube and CinemaNow ones that my BD390 had.
4. Thinner, sleeker physical design.
The not-so-good to bad:
1. Sluggish response in many of the apps, despite the supposedly faster CPU. This is on a fast wireless N network.
2. The main home screen is just kind of ugly (despite a selection of wallpaper backgrounds) and badly laid out. The flashy, simple 8-tile grid of icons on my BD390 was nice. This new layout has a bunch of wasted empty space, the icons are smaller, and I don't like that media-playing from internal HDD or network shares is all grouped into "Movie," along with disc playing. I guess it's OK, just confusing at first.
3. I don't like having to click on Premium, then another icon, then finally on Netflix, in order to get to Netflix (or whatever other Premium app you want to name).
4. The BD390 had Page-Up and Page-Down buttons to somewhat speed browsing through MP3s, videos and photos. (Well, it was still slow, but at least I could go up or down a page at a time.) The BD690 has no such buttons. Sure, you can hold down the navigation arrows on the remote and it will start scrolling faster after a while, but it still takes a loooong time to scroll from A-Z when you have something like 15K songs.
5. The album cover art is kinda small and there is a ton of blank wasted space on the screen so the cover art really could be larger.
6. The free LG apps that I've tried so far are pretty laughable. Not anything to base a purchasing decision on.
7. Clicking on the "Search" function on the dock currently says "Coming Soon!"
The really freakin' ANNOYING:
1. Yes, this deserves its own category: The YouTube app completely blows. What the hell was LG thinking?? They had a nice, fast, functional YouTube UI design on the BD390. The only niggling flaw was having to hit the Display button on the remote to blow it up full screen after it starts playing (and even then it wasn't always the HD version).
But now? OK, I want to watch YouTube. Click on Premium, get over to the YouTube icon, click on that. Wait and watch a little spinning thing while the app takes too long to load (in comparison with the BD390 app). So it loads up and immediately starts playing a loud video of some fool falling down some stairs in slow motion. WTF??
There's a little bar on the bottom directing me to hit the Up arrow to Search or the Down arrow for the next video. So I hit the Up arrow to search, and a keyboard overlay comes up over the video that's playing. By now it's on the second randomly-selected video, which happens to be some fool kid spouting profanities. Well that's just awesome when I have little kids sitting on the sofa next to me.
I start to type in what I'm searching for, and to my surprise and disappointment, it doesn't auto-suggest anything, as my BD390 did. So I type in the whole darn thing. Finally the search results come up...in a stupid little horizontal thumbnail strip on the very bottom of the screen, with each thumbnail dismally small enough to be nearly indistinguishable on my 40" HDTV, and the whole rest of the screen is completely wasted space.
I click on a thumbnail and the vid starts playing. It's an HD-quality video and looks pretty good. It finishes playing, and the next thumbnail video in my search results list starts playing automatically. GRRRRRRRRR!
OK, so I discovered I can hit the Pause button as soon as an unwanted video starts playing, and get out of it. But that's just f'in stupid.
And if that weren't enough, the nice History and Favorites tabs I used to have on my BD390 are no more.
In short, the YouTube app is a total joke. I fired off an e-mail to LG to tell them that, and I hope that if enough people do the same that they'll eventually listen. But why the heck did they downgrade it so drastically to begin with? They had a nice YouTube interface on the BD390. This is many, many MAJOR notches down in quality from that.
So, I'm not sure I'm happy with this thing overall yet. Do I keep it and hope that future updates will fix the glaring flaws? Or do I return it and start over? Have I even had it long enough yet to make a determination? I don't know. But that's where I'm at right now.
