HELP: HD movies stuttering when playing from ReadyNAS Pro ??

Symptoms sound like a buffering issue, but not much more I can suggest as I'm not a windows 7 user. As you may deduce from the other thread, there certainly seems to be some issue with Win 7 and the CIFs support in the latest firmware - I hope someone more familiar can offer a suggestion

IT IS DEFINETLY A READYNAS CIFS PROBLEM!!!

Finally, I tested streaming the HD (1080p) movie from ReadyNAS: stuttering all time, details...see my last posts. Firmware 4.2.11 and 4.2.15 same results. :(

Then i tried streaming from another Windows7 PC (same network): runs flawless, like a charm, no stutters, instant fastforward or skipping chapters...HD streaming at its best :D

This is the proof there is something broken in CIFS support of the ReadyNAS Pro. :evil:

Jedi Council or others, are you working on this???

Many users using the ReadyNAS for (HD/Bluray) movie archive and streaming and watching using W7 MediaCenter or others. It would be a shame if the ReadyNAS does not support HD movie streaming to local clients!!! :oops:

Please let me know, otherwise I have to sell the Pro at ebay and get another brand supporting HD movie streaming....Please help!!!

Thanks, Jan (would love to keep the Pro..)

I have another take on this same problem.

I'm copying between 2 ReadyNAS ProPioneers (backing up one onto the other).
The PC in the middle is a reasonably powered Win7 PC with a Realtek PCIe Gigabyte mobo NIC.
I'm running ViceVersa Pro 2.5 as the backup programme (see : http://www.tgrmn.com/)
Both NASs have the same drives (2TB Seagate 5900rpm drives) - NAS#1 has 5, NAS#2 has 6.
The network is connected by CAT6 through 3 Netgear GS108tV1 switches.

Here's where it gets interesting.

If I start one instance of VVPro2.5 to copy Share#1 on NAS#1 to BackupShare#1 on NAS#2, then I get erratic data rates similar to the Video stuttering data rate patterns.
If I then start a second instance of VVPro2.5 to copy Share#2 on NAS#1 to BackupShare#2 on NAS#2, then I get a nice smooth (and faster) data rate pattern.
(Also works fine with 3 and 4 instances, but the data rate saturates at 3)
The data being copied are video .iso files, each one 7GB or so in size.
Similar results are seen with smaller files down to 500MB or so.

The moment one of the instances is finished, the pattern reverts. Starting another instance recreates the smooth, better pattern.

It's as if NAS#1 doesn't have time to lose/drop the connection when dealing with 2+ read requests ?

PS
I don't get the same problem with drag/drop nor when running copy operations to/from just NAS to/from PC - so is it a NAS problem, a ViceVersa problem, a network problem or a PC OS/Driver problem ?

I have experienced the same problem with Realtak GigE NICs. I posted some details in another thread: viewtopic.php?f=21&t=44713&start=30#p255212

My solution is to use the Windows 7 default drivers and not use the offered upgrades in Windows update.

Thanks, I'll try that, but my install is the 32 bit version.
However, I had a worse problem with the original Win7 installed driver and partly fixed it by updating from the Realtek site.
So everytime I have to reinstall Win7, I always update the driver, but I'll see if the old driver is better.
I never use Windows update, but wait for the SPs.

I'll post the driver versions I use.

An update - I finally updated my Pro to f/w 4.2.15 for which the release notes list the following:

Fixed network dropout issues reported on the Pro, NVX, and Ultra series.

I then re-tried the Reaktek drivers that had been causing stuttering in the past and I again got video stuttering. So, I went back to the Windows drivers and the stuttering went away. There appear to be 2 available drivers, one that came with the Win7 Pro installation I have and one available through Windows Update (with a May date). The May driver appears to work fine for me.

Thanks. To be sure, can you post the driver info that works for you on 4.2.15.
The one I'm using that has the problems listed is : Realtek 25/10/2010 7.31.1025.2010

Here are the details of my successful driver.

The device name is listed as "Realtek RTL8168C(P)/8111C(P) Family PCI-E Gigabit Ethernet NIC (NDIS 6.20)".

The driver is by Microsoft, dated 5/14/2009, Version 7.2.1127.2008

With the unsuccessful driver, I get a different device name.

Hi Folks,

yes, the W7 default driver improves the situation, but does not solve the problem. The W7 client plays HD movies like charm when streaming from other servers, i.e. another W7 PC. This applies to the W7 default NIC driver and the latest Realtek NIC driver.

STUTTERING HD MOVIES (while streaming from ReadyNAS to W7 clients) IS DEFINETLY A READYNAS CIFS PROBLEM!!!

I tested all combinations streaming the HD (1080p) movie from ReadyNAS:
1) Realtek NIC driver (regardless of version) stuttering all time, details...see my last posts.
2) W7 default NIC driver: Movies with lower bandwith consumption starting, running smoothly - if you do not touch Pause or fastforward, if you do so the video stutters again.Probability of stuttering applies very much to HD movies with higher bandwith requirements or peaks (i.e. HD movies with multiple audio tracks etc.)
3) If you stream the HD movie - regardless if using Realtek or W7 driver - from another "server" (i.e. other PC running W7) everything runns smoothly and very (!) fast response to FF, skip chapters or other functions.

This applies to ReadyNAS Firmware 4.2.11 and 4.2.15 :(
This is a clear proof there is something broken in CIFS support of the ReadyNAS Pro. :evil:

PLEASE, can someone from ReadyNAS look into this...? Is anyone working on this???

Many users using the ReadyNAS for (HD/Bluray) movie archive and streaming and watching using W7 MediaCenter or others. It would be a shame if the ReadyNAS does not support HD movie streaming to W7 clients!!!

Thanks, but no help to me in the end as I have the new 8111E version. This isn't in the Microsoft catalogue and so I'll have to use the Realtek versions.
I've tried a number of Realtek drivers and the newest one is better, but I'm also convinced that there is something not right in the bowels of the ReadyNAS CIFS code.
