Just picked up a BD690 on clearance for a decent price. I am a longtime owner of a BD590 upgraded with 1.5TB drive. I was curious to see what improvements if any, were included in BD690. My problems with the 590 were as follows: slow UI, outdated Netflix client, horrible network performance, cannot stream large/high bitrate files without chop, and copies to the HD very slowly off the network. Sadly, the same terrible UI and network performance exists in the BD690 (have not yet tried Netflix because it always says, "Can't connect to Netflix"), and now it won't play any of my .TS files that are in 1080i (it play the 720p ones ok). The BD590 in comparision has absolutely no problem with my 1080i .TS files. Ugh. I've skimmed this thread and see folks mention the same problem, but I haven't seen any solutions offered short of remuxing it into an MKV container or reencoding at 720p. Is that still the case? It's really ridiculous that the older 590 plays these .TS 1080i files and the supposedly more advanced 690 does not. I'm at the latest firmware that's out as of today.
Also, for those that have upgraded their HDDs, can you tell me what model number works perfectly with this player? I ask because I'm worried about Advanced Format drives in this player - I upgraded my BD590 with a WD15EADS, which is non-advanced format. It is near impossible to find a non-AF drive these days though... does the BD690 play nicely with AF?
All in all, fairly disappointed in this player, even at the price point I bought at, mainly because i had high hopes for improvement over my current model. Will keep it because I can still find a use for it with other files and as a disc player.
