Can't Play 18mb or higher TSfiles on 2.0

Sun Aug 28, 2005 5:21 pm

Hi All

Hopefully some one can help out with my problem.
I am running 1.5.18 at this time with ts player 1.d
and have no problems playing any ts files.

But soon as I try any of the 2.0 beta's , 2.0.34 works best.
I can play 9 to 12mb ts files just fine, but anything higher will
play ok for about 20 second then will start to studder and then lock
up the HD1000. I tried playing them directly and with M-Play with
the same result . Any Ideas? Is anyone else seeing this?

Thanks for any help in advance.

For me, SMB maxes out at about 21Mbps. I haven't check lately, maybe it went down? Are you using SMB or NFS? Are you wired or wireless?

The FAQ for the PB says SMB max is 20megabit/sec. So, 18megabit/sec (if that's what you mean by '18mb') should play fine. I've played higher and they've worked on mine (wired connection, 2.0.34 fw). I AM considering switching to NFS shares vice SMB shares though, as the FAQ says the PB max from an NFS share is 50% higher (30megabit/sec).

You might also try a UPnP server as there is considerably less overhead with HTTP (used for UPnP) than for SMB.

Sorry for a newbie question -
So how do I know which protocol(SMB or NFS) i'm using?
And how do I tell the PB to use NFS?
I think my NAS(Infrant X6) supports both SMB and NFS.
Right now, I'm running everything by default. And having problem(no audio, glitches in video) with TS stream above 18mbps(as reported by mplay hitting info button).

My setup is wired back-to-back PB to NAS.

BTW, thanks to Marcelo3d and TheEndless for Mplay - great app.



Thanks,

locman.

Dito on that

I run a 2.4 gig p4 with windows xp home ed. and just set up the folders
I want to share with the R1000. I am hooked to the internet thru a router and cable modem that goes to the roku. Nothing else is hooked to the system . I am a wired network. and use a swap file.
Like I said before, works just fine with 1.5.18 , why not with 2.0xx .

Thanks again

P.S. I know this will work in the end
and I do love the product , even if I have to stay at 1.5.18

The roku setup app only allows you to configure SMB shares at this point. You need to telnet to the device and issue unix commands to mount an NFS share. These commands can be scripted and saved to a .roku file so that you can run them from the GUI.

Search this forum for "NFS mount" and you will find several threads on how to set up NFS mounts.

Also keep in mind Windows shares are SMB. I think you have to have a Linux machine (or similarly a NAS running a *nix-like OS) to be able to do NFS. Or does someone know of an addition that can be made to Windows (XP Pro) so that it supports sharing as NFS?

There was a post some time ago by someone that got Unix Services For Windows to export an NFS that the HD1K liked. There are other NFS server for Windows too.
So, your statement is mostly true, DEFAULT Windows installations use only SMB.

Yes, you can use Windows Services for Unix 3.5.

I've tried it myself, works well, but can be tricky to get the initial setup working.

Coolness! I'll give it a shot. I've got some HD demo clips from overseas that HDTVtoMPEG2 says are in the 25+ Mb/sec range and they're breaking up on playback from a WinXP SMB or Samba 3.0 Linux share.

Well, I dl'd WSU from MS and I've installed it on my XP box. After a reboot we'll see what happens but reading some other posts on the board hear it looks quite painful to setup.

Using the info at http://www.troubleshooters.com/linux/nfs.htm was pretty easy to setup NFS on my Linux box and was then able to mount that share on the Roku.

I did a quick initial test using an 860MB mpg2 Program Stream HD demo file. Using the time command and copying from the same file from the NFS share and SMB share to /dev/null, Linux network monitor reported the transfer averaged 2.8MB/s from the SMB share, 7.8MB/s from the NFS share. The time was 1m53s via NFS, 5m10s via SMB. That's quite an improvement in raw throughput.

ProjectX says the source file is 17.5Mbps average bitrate. Over SMB, the file was unwatchable, over NFS it's still not watchable with either MPlay or the built-in player. :(

Trying to watch the same clip on my WinXP machine, WMP6.4 stuttered and skipped. VLC 0.8.1 appeared to play through flawlessly. My Windows net monitor reported the filestreaming from my Linux server at an average of ~20Mb/sec.

So...I've got some 30+ Mb/sec .ts files somewhere, I'll see if the results are better on the Roku as a .ts vs. a PS.

I have the same problem with streaming off a Maxtor NAS drive. With SMB I can stream ts files from the PC to the Roku and they play fine. From the NAS drive they stutter above 18 Mb. But testing the drive I can get 62 Mbit transfer rate to the PC and all the files play fine on the PC across the network. Just wish it would work as that's what I got the NAS drive for.

So does roku work fine with over 18Mbit/s files over network from working NAS device? Over NFS or SMB?
