Poor streaming connection/speed
ReadyNAS NV+ v2
WNDR4500
2 x Powerline AV500
Tvix N1 Network Player
Hello. My first post at the ReadyNAS forum (previous Stora owner!).
I hope someone can help me; I'm getting really frustrated with my 'streaming experience'. Alot of folk out there seem to be able to stream HD using the ReadyNAS, so when my Stora had problems, I decided to 'upgrade' to the NV+ v2. I have spent quite a lot of money with Netgear trying to play HD media over my network; over the past few months I have been slowly upgrading my older Powerline adapters to the AV500, invested in the WNDR4500, as well as moved 'up' (?) from the Stora to the ReadyNAS, but I still cannot play HD video from the ReadyNAS through the WNDR4500 and Powerlines to my Network Player.
I did have a gigabit switch (at the Network Player end of the Powerlines so my Sky box can get online, but even with this now removed from the 'pathway' there is no improvement.
I know it's not an issue with the player as the same file will play beautifully (even at double speed) when I attach a USB2 drive directly to the player.
There is such a wealth of settings that could be made within the router and the ReadyNAS, so I'm hoping someone could give me some guidance? I have also upgraded all my cables to CAT6 (there are a couple of CAT5 but these should be OK?)
My setup is pretty basic...
ReadyNAS ---> Router ---> Powerline ---> Powerline ---> Network Player
The Powerlines are both plugged directly into the mains (no extensions). All the devices I have should (according to the literature) be capale of supplying more than one HD stream, so what have I got wrong?! Anyone got any advice please?
On the ReadyNAS I have RAIDiator 5.3.9 and the following Services; SMB NFS, ReadyDLNA, UPnP, HTTP, HTTPS and genie activated. It is setup as X-RAID2 and is fully populated with 2TB WD Reds showing '827.7 GB free of 5.4 TB'.
On the WNDR4500 I have QoS rules giving the ReadyNAS 'Highest' priority.
I had some great support from the Stora forum, so I'm hoping I can finally get to the bottom of my new problems here! Thanks in advance, guys!

- btw what firmware are you running in the v2?
- Firmware RAIDiator 5.3.9
A check for updates says I'm running the latestfirmware.
Yes. 5.3.10 is still in beta.Weevil wrote: Firmware RAIDiator 5.3.9

I asked in part to confirm that you have a v2 (which you do). The labeling is confusing, and many v1 owners mistakenly think they have a v2.
Your gigabit read speeds of 25 MB/s are about right for a v1, but are fairly slow for a v2. However, you are still 4x faster than what is needed for bluray streaming, and 2x faster than what fast ethernet can carry. So I suggest that you not worry about that until you get streaming working to the twix.- I've had uncompressed DVD files (various incl mkv's and ISO's) streaming to the tvix for some time with no performance issues at all. But when it comes to an uncompressed Bluray mkv, it will not play properly at all... lots of 'stuttering', no audio, long pauses etc (unwatchable). The very same files plays perfectly when read from a USB2 drive directly attached to the tvix, so I think it's safe to assume that the player is OK and that it's a network or NAS speed issue?
After some more testing using another laptop with a gigabit NIC, I get read speeds of ~25.36 MB/sec before entering the Powerline, and 6.95 MB/sec after the Powerline at the other (tvix) end. I don't know if this gives you any more clues?!
You mention that 25 MB/s are slow for a v2... how can I improve this? - (a) Full BluRay requires about 60 mbits/s (7-8 MB/sec), and you are not getting that through your powerline network. A DVD requires 12 mbits (1.5 MB/sec) - which you are getting. So the powerline performance probably explains the stuttering. You can confirm that by taking the powerline out of the equation.
If you have an ethernet switch you can borrow, try moving the NAS to the twix, and connecting them to the temporary switch (also connect the powerline to the switch).
Or if you have a TV or digital monitor near a gigabit ethernet connection, you can move the twix...
(b) Probably best to sort out one problem at a time. If you want to set the twix playback issue aside for now, we can start on the 25 MB/s throughput issue.
BTW, your DVD files are compressed (mpeg-2 video, and likely dolby digital audio and/or DTS). All video is compressed, and most audio. - Hi,
I have a long CAT6 cable somewhere. I'll connect the tvix to the the router with this - it should almost get into the room it usually inhabits and , together with a long HMDI cable, I can connect the tvix to my AV setup. Although I'll get some earache over the cables everywhere ( :roll: ), this will take the Powerlines out of the equation and enable me to establish that the tvix is actually capable of playing Bluray via the network from the NAS. As mentioned in an earlier post, it will play Bluray files from an attached USB2 drive, so I'm assuming it ought to play OK.
What's the best way of tackling the low throughput from the NAS?
Sorry - I meant that the DVD files are not compressed any further than they already are on the original DVD - they are direct ISO backups. - Hi,
I've just done as mentioned in my last post; Cat6 cable from router to tvix directly, taking the Powerlines out of the mix. The Bluray file played slightly better, but not well; it was still jittery with interrupted audio. After 'auditioning' the file, I replaced the tvix with the laptop and did another NASTester test; 24.96 MB/s average reading speed - similar to that which the PC reads at over the network, and the PC plays the file over the network with no issues. Maybe the tvix isn't capable of reading at this sort of rate through its network? Although as mentioned, it plays fine on the tvix from a USB2 drive.
Using VLC media player on my PC to see the content bitrate, the file I'm playing spends quite a while showing >35,000 kb/s, with the (very rare) peak to 70,000 kb/s. Maybe the file is just a particularly nasty one?! (It's a Bluray of Episode 1 of Firefly for what it's worth).
In your opinion, am I looking like I may need to consider a new network player with a gigabit LAN port that can buffer files more effectively? Or, if we can improve the performance of the ReadyNAS, re-siting it to sit alongside the tvix?
I would like to improve the throughput from the NAS if possible, if only to improve file transfer times.
If you're not sick of hearing it again... Thanks for your assistance - it's much appreciated! Weevil wrote: 24.96 MB/s average reading speed. .... >35,000 kb/s, with the (very rare) peak to 70,000 kb/s.

Am I right in thinking that upping the throughput from the NAS should solve the problem?
Be careful comparing MB (megaBYTES) with kb (kiloBITS).
24.96 megabytes per second is approximately 200,000 kilobits per second, so if the numbers you posted are accurate, the NAS throughput is already 3-6 times as fast as you need.- Hi,
Thanks for looking in... That's why it's so frustrating that the file won't play properly... a connection that is transmitting at just under 25 MB/s yet won't play a Bluray file that peaks at ~8.5 (according to VLC's 'real time' reporting during playback). Hence why I'm worried that it's the player's handling of LAN traffic that's at fault?
Cheers,
Stephen - How are you accessing the file? If you are using SMB, then try NFS. NFS is often more efficient for linux devices (most media player devices use linux), and is supported by your player.
What format is the file in (ISO, m2ts, MKV, ...). If it is not ISO, then perhaps download mediainfo from http://www.videohelp.com/tools/mediainfo, and have it analyze the the file. Select the "text" view, and cut/paste it into a followup post.
