Issue streaming files >4Gb via PS3

I just posted this item to the D-Link forum site, but thought I would post it here as well in case it is of interest to others here...

Last week I received my new DNS-323, rev B shipped with v1.05 firmware. I followed the setup procedure and installed the two 1Tb drives I also purchased (Western Digital WD10EACS) in a RAID 1 configuration. I then followed the upgrade procedure to install v1.06. The DNS-323 is then plugged into a Edimax Gigabit switch, as is my PC and PS3.

The main reason for purchasing the DNS-323 was to allow me to watch television shows on the PS3 which I had previously recorded through my PC tuner. The DNS-323 is always on and has heaps of disk space so I wouldn't need to waste time transcoding.

I recorded a 90 minute television show on my PC in MPEG2 format with an extension of .MPG. The file is 4758Mb in size. I can confirm that the file plays on my PC using Windows Media Player and plays in full on the PS3 when streamed using the Nero MediaHome uPnP server on my PC. I then copied the file to the DNS-323. The file plays in entirety from the PC via the mapped drive.

However, when viewed on the PS3 via the DNS-323 uPnP server, the file size is shown as 662Mb and only the first 12 minutes of the show are played. The playback actually stops after 12 minutes. From the PS3, if I then try to copy the file to the PS3’s internal drive via the DNS-323 uPnP server, I only receive a 662Mb file and similarly only the first 12 minutes are visible.

To further test this, I then recorded a separate 120 minute piece which resulted in a file of 4889Mb. Again, this worked fine from the PC via Nero MediaHome but when viewed via the DNS-323 uPnP server, the file size is shown as only 793Mb and only the first 20 minutes are shown. The same issue occurred when copying to the PS3 internal drive via the DNS-323 uPnP server as before.

On request by D-Link, I tried a different format. I ripped a DVD into a single .vob file which exceeded 4Gb with the same results as the .mpg. In all cases the difference in file sizes is exactly 4096Mb ie 4Gb!! This points to an issue with files in excess of 4Gb. Given that the v1.06 firmware release notes clearly state a fix to “UPnP AV Large file( > 4GB) issue” and an enhancement to “Support PS/3”, this led me to believe that this would be OK but it appears not.

Although I do not think this has anything to do with the PS3 given that it plays the file fine through a different uPnP server, it is a standard 40Gb unit with the latest firmware (v2.60) installed.

Also on request by D-Link, I restored to factory default, re-installed v1.06 and then reformatted the drives to RAID-1 just in case this resulted in a miracle. No such luck.

I have been in contact with D-Link support (in Australia), so am waiting for a further response. However, in the meantime, I thought it might be a good idea to post to the forum in case others were still experiencing a similar issue with the latest firmware.

Re: Issue streaming files >4Gb via PS3

I too have a PS3 and that is where the problem resides.  The PS3 missreads file sizes. I discovered this problem when I was setting up a new game. It is a problem with the way the PS3 reads memory and available hard drive space and is due to Sony using code fom long ago and far away.  Check some of the ps3 forums to verify.  Wheter Sony will fix it anytime soon or not is a good question. Add 300 mg of dead space to your test file and it will play.

Re: Issue streaming files >4Gb via PS3

Thanks for the reply. As I said in the original post, connecting to the uPnP server on my PC (running Nero MediaHome), the PS3 showed the correct file size. This is exactly the file size shown on the PC file system so it appears that the PS3 is capable of doing the right thing, just not in conjunction with the DNS-323 uPnP server. So:
Option 1 - PS3 is innocent (in this case!) and the DNS-323 uPnP has a bug
Option 2 - DNS-323 uPnP is innocent, PS3 has a bug but it works fine with Nero MediaHome somehow
Option 3 - Some other combination I haven't thought of

Given that the firmware update talks about resolution of a 4Gb issue with the uPnP server, I still think Option 1 is the most likely. I am going to try installing a uPnP client on my PC that can connect to the DNS-323 just so I can take the PS3 out of the equation.
