I hope you can help as I have reached the end of the line. I am a (retired) IT professional so I have a method when I try to debug a situation, and I really do not know what to do now. I suspect there is an incompatibility between Twonky and my brand new and not inexpensive Panasonic Bluray player. This will be a long note but I hope you can make some suggestions or perhaps actually have a fix.
1. BluRay player Panasonic DMP-BD85, firmware upgraded, purchased in France at Saturn the big chain.
2. Network attached disk Iomega Home Media Drive, 500 GB, attached to my home ethernet. My network is spread over three buildings and from the location of the Iomega (plugged into the main gigabit switch) there are two other switches to traverse to get to the Panasonic.
3. Second network attached disk WD MyBook World Edition, recently purchased on the theory that my Iomega was not up to snuff. That is where I found Twonky. I do not know if Twonky is running on the Iomega.
Here are the scenarios I have found:
A. Connecting the Panasonic Player to the network and loading up my films in the Iomega, I can browse my network to see the list of films, but in the title list, neither the time the film was recorded nor the duration, is shown. When I click on a film to play, I get the terse message "Cannot play". I tested several of them burning them onto CDs and onto a USB stick on the theory that the formats were bad, but they play fine locally on the Panasonic.
B. On the theory that the network had too much latency caused by the cascade of 3 switches, I moved the Iomega to the cinema room and connected it to the same switch that the Panasonic is connected to. Same symptom. I can see the list of films, the Panasonic and the Iomega are talking DLNA sort of, but no film can be seen.
C. On the theory that the Iomega had lousy DLNA software, I downloaded a trial version of a DLNA server (I did not know about Twonky at the time) called "Mezzmo" installed it on my WinXP machine, which can see the Iomega as a network disk, and added the films there to the Mezzmo catalog. When I go back to the Panasonic, the films on the Mezzmo server are visible in the list, the time of saving and the play times are shown, but they cannot be played. A slightly different message comes up.
D. On the theory that there was a latency problem on the network caused by the Iomega being too slow, I moved a couple of films over to the Win XP server and bingo I could see them and play them. Once or twice. Now, I cannot. So that was not a definitive fix. In any case, my desire is not to have yet another Windows machine in this house which I will have to build and maintain to house my films. I want to use dumb-ass media servers if possible.
E. I talked to the people at the store, who badmouthed Iomega and told me to buy a WD which was sure to work better. I did, plugged it into the network, loaded up some films, and, drat, exactly the same symptom with Twonky software running on the WD.
So I am totally stuck. It is hard to believe that the Panasonic has lousy DLNA but who knows. My next step in this brute force approach is to bring the Panasonic back to the store and change to, I don't know, a Samsung, even though the sales guy said the Panasonic is alot better in terms of quality when reading disks. Obviously in all these tests I made sure the firmwares were at the latest releases.
My network is totally vanilla and although the cabling is Cat5 it is all new. The switches are of good quality. In any case the issue of latency does not seem to be the problem as the same exact symptom appears even when either the Iomega or the WD/Twonky are attached to the same switch as the Panasonic.
Do you have some ideas for me ? Is it possible that the Panasonic is not running a good DNLA client ? Other things I can try ? I have like 7 days to return all this equipment to Saturn and start over, so if I need to give up, please tell me. Before I got talked into the Bluray player with DLNA I used a very hokey little media player from Verbatim that read my files on the network just fine, but did not produce HDMI and of course no Bluray so I thought this was my chance to upgrade to a better future. Please help, and thank you in advance for you time.
