Thanks for the suggestions, guys...
Kludge nailed a couple of my thoughts on the head.
I like my Samsung, and wouldn't ditch it... My father and I talked, and he wanted a Blu-ray player but like me also has a bunch of HD-DVDs... and his HDTV has less connections than mine... so it would be more convenient for him to have the Samsung and let me have multiple players connected.
I ruled out a new Samsung on principle... as we have been discussing for seems like years now... Samsung hasn't won me over with their lack of response to recent playback issues. Fortunately, the affected movies so far aren't ones that my father owns or wants to own... so he may be ok without that playback capability for those movies.
I have a Sony turntable (not currently connected) and a nice Sony STR-DH800 audio receiver. My previous audio receiver was also a Sony, incidentally.
I have a PS2... my sister has had a PS, PS2, and now a PS3.
Like Kludge noted, I figure Sony still has a lot of skin in the game to support Blu-ray... so I figured even their "bottom of the line" players would get better firmware support.
I couldn't really find any bad Sony reviews... and we had to make a trip to Sam's tonight for some other stuff... so I picked up the BDP-BX18... basically same as the S185 except it also includes an HDMI cable in the box.
I'm looking forward to hooking it up and seeing some of my movies that I couldn't play in the Samsung! I'll still be keeping up with the Sammy, though, and testing movies now and then in it especially if they ever get around to any updates.
Yeah baby! It's Halloween!
