my setup has no lag at all. however, it takes a while to set it all up and if something happened, I would prefer to just replace one device. besides, I prefer to have a remote vs using ipod/iphone
WDTV Live can access shared folders. works like a charm. i've got 4 of them running.
You mean you currently use the raspberry pi? If you want to be able to recover from something happening use a tool like win32 imager or your tool of choice to make an image of your SD card. If the card ever corrupts or something else happens just get another SD card same size or larger, image it with the image and you are done. It'll be an exact replica of how it was setup.
As for the remotes you can look here for supported remotes or a DIY setup: http://www.raspbmc.com/wiki/user/configuring-remotes/
I use a Pi in the bedroom and it works like a charme. Its running openelec gotham build oc'ed to 1000mhz. I use a SD-Card for boot and a usb stick for the rest of the OS to avoid filesystem corruption. It's much, much faster than the wd-live i setup at my moms. My media is sitting on a i3 openelec system in the living room.
Edit: BTW no need for a Remote on the Pi it has build in CEC so you just use the tv remote.
One caveat on WDTV Live (gen3 w/ Netflix support) - it will take over your network. It regularly forces master browser votes and tries to take it away from other devices. Anytime I reboot my server I have to reboot the WDTV live afterwards to pass master browser back to the server.
If the WDTV live was actually good at being a master browser this wouldn't be so bad... but I am regularly unable to see all devices on my network when WDTV is master browser.
The only other issue I have had is overheating when playing netflix videos.
If it were not for these two issues I would have WDTV live on every TV in my house.
My understanding is older versions of WDTV live have alternative firmware options that lower the browser priority, allowing it to play nicely on the network. However, they do not have netflix support, which is a significant portion of the media consumption in our house (we have two young kids).
So I finally bought myself a WD TV Live Media Player. I love this thing, it's definitely one of the best purchases that I've made in the past few months!!!
Even though it has WiFi, I decided to run a network cable from our 2nd bedroom / office (where to modem & router are located) up to the attic, over and down into our bedroom. A couple of years ago I ran the coax lines up thru the walls, so I just needed to run the network cable thru the already drilled holes, etc. It gives me a bit more piece of mind with it being hardwired. A 30 ft cable and 2 new keystone plates cost me under $10, so it was worth the minimal amount of time and money.
It literally too me longer to run the new network cable than it did to setup the WD Live player. After booting, it did a few firmware updates, rebooted and then loaded its home screen. Then I logged into my home server thru the WD Live player and my network folders showed up. Before I would have to take my laptop back and forth between our living room TV and bedroom TV, it's so much nicer not having to carry the laptop, its charger and a HDMI cable up and down all the time.
As of right now I'm only using the WD Live player to access content that's on my server, but my hope is to slowly be able to move toward only using my home server and Netfilx / Hulu so I would be able to get rid of cable. My next project is going to be getting a HTPC set up for my living room TV.
I had previously tried a "reset" thru the home screen's system tab and it didn't seem to work. So tonite I tried the reset with a paper clip in the reset button on the bottom of the device. Still no luck. So I'm in the process of doing a firmware roll back.
I'll update after the roll back and let you know how it goes.
