Best firmware for RNDP2000 after OS6 upgrade

thanks stephen, yes WD30EFRX and WD30EFZX. and yeah no idea re: telnet blocking. it was weird because every 5-10 attempts the login prompt would appear (so if the router was blocking it wasn't very good at it..), but the connection would always fail before i could complete. either way once the router was bypassed it worked fine.

any thoughts on which firmware to run? i ended up going to 6.9.6. Any reason to go to 6.10? (esp. given DLNA issues below?)

i have the sonos library up and running again, but unfortunately still can't browse media on the nas thru the bluray player. initially i thought this might have something to do with smb 1 (as with sonos), but now i'm thinking it's got to do with DLNA. I know it's working because I can see the nas as a media device on the network (under network on the computer, and under DLNA on the smart tv...some videos will play that way), but it refuses to show up on the oppo player. worked fine until a year-ish ago...strange because nothing changed. i wanted to continue troubleshooting (the oppo is wired with ethernet behind an asus switch...i thought about bypassing the switch, and/or trying via wifi since that seems to work for the smart tv...), but i ran out of patience. it's an older unit (bdp-103...oppo stopped making bluray players in 2018) and right or wrong i've convinced myself that it's the culprit. too bad because it was so easy to browse the nas on its "network" interface...just navigate to your file and play it...no add-ons...it just worked.

plex installed easily enough. i bought an nvidia shield pro (consolation prize for the failed troubleshoot), which will replace our roku and should give me media server browsing with plex to replace the lost oppo player interface. still looking for a firmware recommendation but either way, cheers!
