Thanks for the recent work to fix both series view within MC and address the login problem from Netflix...both now work from my system in Theater View.
This is just an enthusiastic MC user's spectator's report, so fwiw, disclaimer, take the vowels out of my post, etc...
I suspect Netflix Streaming is considered a reluctant guest in the House of JRiver.
I've browsed the Netflix development forums and I can see why. From what I see, there is no full API, playback requires proprietary player, and limited if any development support. Plus, they flat out break things by changing the interface that is available. Netflix recently caused a login break; it came back online quickly, but in the future, who knows! Microsoft got inside access for the WMC interface, but they're Microsoft and tend to get inside access. No other software player that I know of can offer anything other than a link to the player and/or information scraped off from the main website. All other non-web players are hardware-only: Roku, Apple TV, PS3, etc. Copyright paranoia on behalf of Netflix has to be the main factor at play here.
Bravo to the developers for the work so far in building the current solution.
If possible, I'd love to see the following improvements:
1. Netflix behaves differently depending on whether IE 9 or Chromium is selected in MC Options. IE 9 works best, but often forgets the password login when you close and re-open MC. Chromium remembers the login info, but doesn't default to full screen or have remote controls that work.
2. Some genre categories are stuffed with older titles, it would be nice to have more current offerings.
3. The TV Series category only lists single episode shows. Most of the better TV titles on Netflix are multi-episode.
Personally, I'm very thankful for the work so far developing this feature, I use the Theater View Netflix menus all the time. Recent integration of background images has been especially nice. It would be great to see continued improvements...if they are possible!
