HELP: HD movies stuttering when playing from ReadyNAS Pro ??
Hello, So sad, I am getting really frustrated. :? I purchased a new high performance HTPC with Windows7 (for running Media Center), PowerDVD10 and a ReadyNAS Pro to watch and archive my HD movie...
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 ?
