I have been using MedeBO 1026 for some time now as it was in my opinion the best firmware.
Recently I have been having some lockup issues when playing movies and this happens randomly, not specific to a certain file.
So I decided to try this firmware as the refreshed, faster Gui sounded promising.
The Gui is nice, the ability to change view types from list, to preview to Thumbnail is decent.
In video playback, I love the video info, subtitle control and skipping through the video.
Web Remote for Iphone is awesome, works really well and fast.
No lockup issues so far as described above.
Movie, Photos recently added menus only work with drives attached via USB or internally.
Slight menu lag when selected episodes of tv series, I always find when I hit enter, its still catching up on my last down press.
No watched indicator. This is a really nice feature in MedeBO.
No AAC audio decoding via optical. A number of my MKV bluray rips are encoded in AAC. The MedeBo also seems to have a problem with this decoding and sends the audio as stereo but this firmware doesn't even try, its dead.
Subtitle set to on by default, every time you watch something with subtitles that you dont want, you have to turn them off manually.
If I could have this firmware with AAC, watched indicators, subtitle setting in main menu and scanning on network shares for recently added, I would keep it, but its back to MedeBO for me.
