C200 and streaming from NAS, problem with video playback.

[Carl-Wilhelm]

Hi everyone. I hope this is the right place to put my question.

I have a problem with my C200.
The problem i have is that i cannot get high-resolution videos to play without studdering and stopping. This normally comes when the stream exeeds 15Mbps (as far as i have seen).

I stream all my videos from my Netgear ReadyNAS Duo V2 with two Segate 2TB drives.
When i copy files from a computer to and from the NAS i get around 50MBps speed. The NAS is connected to my the network via cable and 1000Mbps connection.

My PcH C200 is connected to my network via cable, and i have set the settings to 10/100 Mbps, and i use Dynamic IP via my DHCP server.

I have mounted the NAS as a Samba share with the correct IP address, foldername and sharename.

I have tried quite a few different things:

• I have tried a number of different switches, both 10/100Mbps and 1000Mbps switches. No difference.
• I have tried all the different partition types on the NAS. No difference.
• I have tried different drives in the NAS. No difference.
• I have tried to use a NFS connection in stead of a Samba on the C200, but i cannot get access to the NAS with NFS.
• I have tried different cables. No difference.
• I have tried to transfer the same exact movie to a USB disk, and then it works perfect on my C200.
• I have tried to stream the same exact movie from my staionary computer, and then it works perfectly!
  

When i start a movie, it seems to work fine for 5-10 minutes, then it starts to studder. I can pause it, and restart it and it works again for everything from a few seconds to a few minutes.
It seems that if i pause it for a loonger period of time, it works loonger than if i just do a quick pause and then play again.

I have searched the forum to try to find a resolution to this, but could not find anything.

I have also talked to Netgear about the problem, but since everything works fine if i play the movie on a computer, and the transfer speeds seems OK, everything must be (??) fine with my NAS.

Hope i have given a good enough explanation of my problem, and i hope someone have a solution.

Thank you!

i have my ethernet conf. on auto and i have completly no problems playing any file from my nas (dvd, mkv, bluray iso's) so you can try that
and my tcp recieve window is on 5290 bytes

Thanks for the suggestion, but i normally have my C200 connected to a gigabit switch, and if i put it to Auto, it does not connect at all to the network. If i set it to auto and connect it to a regular 10/100Mb switch, it works fine.

This all points to the NAS, streaming to a PC is way different then streaming to the PCH, The PC will request data for as much as it can buffer, the pch just asks for a steady stream with little buffer, So if your NAS Slows down a bit you would not see it on a PC as it may have received enough data in cache for 10 minutes ahead of the point you are at. And as the PCH plays from a pc in same network setup just fine supports this theory even more. I would try to see if the NAS has jumbo frames and if so try turning them off

Hi again.

My NAS does not have Jumbo Frames support, at least as far as i could find out.
Is there any way to get the PCH to buffer some video instead of relying on a constant stream?
