First of all great job on the Rasplex client, however I am a bit dissapointed with the overall speed and performance of Rasplex.
- When browsing through the archive/sections is takes 2-5 seconds before things show up, even when its cached.
- A Huge section with lets say more than 100 things in there takes ages (a minute) sometimes to open :(
- Sometimes with some movies I get no video while subtitles and audio show fine, I dont have this problem on the mac mini or ATV.
- Direct play is most of the times not really doable it just stutters every xx seconds, so i guess best option is to keep remote quality to around 12mbit to keep it playable for now. This behaviour does not happen on a Macmini or AppleTV2.

Any idea on these things? Will this be fixed?
These will all be fixed, they are all known issues. RasPlex is still in the crib :)
Keep up the great work mate, if you can fix those things you have a winner Im sure of that!
Once the time is there, and those cases look stunning I might have a whole bunch of peeps in the Netherlands buying one ;)

Maybe it has to do with wifi vs wired network connection? I haven't been able to test it on a wired connection, but I noticed some choppiness as well when using 1080p Direct Play over wifi. FIgured it was due to the wifi being too slow to process all that data.
Well, thats actually up to your wireless configuration tbh. Im using an Airport Extreme with 450mbit, it gives me enough speed for 1080p directplay over wifi, even when using the 2.4 GHZ band
Direct Play works perfect with a wired connection. Actually the only thing I can't fault RasPlex is how good everything is once you get to actually watching something. :)
If the menu choppiness gets fixed I will fill my house with rPi running RasPlex complete with the amazing cases.
Yeah 0.1.35 is a huge improvement. I can see some great things coming in the future. If anyone else is running into performance issues like I did after a fresh install I recommend bumping the cache from the default 5% to 30%. Updated to 0.1.35 last night and man does it fly now! Well done team!
For me its still not useable enough, even with 0.1.35. Changing menus and going through sections is still unresponsive for now so im gonna stick to the GoogleTV till this is all better :P
Can someone explain the cache a bit more? I wondered what increasing the cache size would do... is there an optimum number? Is it limited by the size of the SD card?
This option corresponding to cache is the amount of the movie which is buffered for playback. this could eventually improve choppiness of playback if you are having serious networking tranfer issues, but it should not change anything to the GUI responsiveness.
- 0.1.35 speed improvement should be very noticeable as the patches that we made with tobias have divided by about 10 the fanouts loading time. now they should load in around 1 ~ 2 secs for a full section (instead of 20~25 secs before)
- also the cpu usage has been reduced of about 30%.
We still have some hope on optimizations but as of now, the perf gain expected will be lower in comparison to what 0.1.35 brought.
I notices some choppiness with MKV files that had DTS audio. Has anyone else seen this?
Pi model B with 512 memory wired connection.
Yep. Same here, same config, but I would more call it a stutter/pause every 2-3 seconds. 95% of my video collection is 1080p DTS encodes, so pretty much everything is choppy (except for those few with DD audio tracks). If I force transcoding, it works, but I'd much rather not have the CPU churning away if its not necessary.

Does you receiver handle DTS? If it does then make sure the DTS section under the Preferences - > System -> audio is turned on and it will then just pass it through to your receiver. I find in pass through mode I can play 1080p with DTS just fine. If you don't have that on then the DTS audio needs to be transcoded either on your PMS or the rasplex client. Work is being done to try and make DTS trancoding work on the rasplex client but right now it just doesn't have the performance.
I'm not using the Pi as part of my primary home theater setup, so no receiver. I'm finding that if I force transcoding, any videos I attempt to restart (not at the beginning) just display a gray screen. I'll keep tinkering to try to find the best settings.
I think the stuttering is caused by the pulldown. Did you set the "adjust the display refresh rate to match the video" in the settings? If not then movies encoded at 23.976 have to go through a 2:3 pulldown to get them up to 29.970 (so to display properly at 60Hz)

Yes, I have that set to always. Also set Vertical blank sync to always enabled. Everything I'm reading on the Openelec and Rasbmc forums suggest as much (having the Pi decode the DTS track maxes out the CPU and thus causes the stuttering). I think I'm stuck either forcing transcoding (which has the gray screen issue on all playback not starting at the beginning of the video) or waiting for additional DTS improvements to trickle down from the Frodo code... Aside from that, Plexbmc is pretty slick. Just a bummer that the vast majority of my movies won't play smooth.
