I purchased an OPlay about a year ago. It’s been great – uses less power than my former HTPC AND the wife likes the ability to navigate via remote only better than my keyboard/mouse/remote combo from before. She (and I) misses the XBMC interface though. That interface is MUCH better than the ASUS one. But who can complain about 14 watts of power and the size of the unit?

So why the post? I was having problems playing Bluray ISO rips. DVD ISO’s played just fine. Bluray m2ts files played just fine. Bluray ISOs would skip quite a bit in terms of the video – audio was always working via the HDMI connection. The odd part was the same files would play just fine over the external USB powered Hard Drive without skipping.

2.5GHz Pentium Dual-Core
1024MB DDR2 PC6400
4X 1.5TB 5400RPM SATA in RAID5 (about 4.2TB usable)
FreeNAS 0.7.1
Gigabit Layer 3 switch

I had set the freenas settings as follows:
Send/Receive buffers were set to 65535
Large read/write was set to on
MTU was set to 9216 (jumbo frames)

Still it was skipping. Since it didn’t happen on the external drive, I assumed that the network was to blame. After a little bit of research I found out that Samba is not nearly as awesome as NFS.

So, turn on NFS on your freenas:

Path of /mnt/raid/Multimedia with Network of in my case

Then, telnet to your OPlay and make a few minor settings:

Open Putty
Telnet to the OPlay
Login as “root”
mkdir -p /tmp/ramfs/volumes/core
mount -t nfs -o intr,nfsvers=3,rsize=32768,wsize=32768,hard,udp,nolock /tmp/ramfs/volumes/core

If you get an error, you did something wrong. Obviously change the IP:/directories to be that of your environment.

If it works, move onto making this a startup script.

cp /usr/local/etc/rcS rcS.old
vi /usr/local/etc/rcS
Scroll down to the end of the file, then press “i”
#Mount NFS
mkdir -p /tmp/ramfs/volumes/core
sleep 15
mount -t nfs -o intr,nfsvers=3,rsize=32768,wsize=32768,hard,udp,nolock /tmp/ramfs/volumes/core
Press “esc”
Type “:wq” and then hit enter

You should now see your NFS share on your OPlay’s local disk area! Yay!
AND no more skipping issues! YESSSS

I’m running firmware 1.28 NTSC.
