Poor Performance with Panasonic TC-P42ST30

Post by audiomr » Sat Sep 17, 2011 7:33 pm

I recently got a QNAP TS-219P+ NAS, which has TwonkyMedia built-in (version 5.1.6, I think). A primary application was to be streaming videos to Panasonic Viera plasma TVs, including a couple of TC-P42ST30s I already have, via DLNA. I found this version would connect with the TVs reasonably quickly and display JPEG photos just fine, but when I pulled up a 1080i MPEG-2 video file, the TV misidentified it as MP4, and when I tried to play it the screen just went blank and stayed that way. This happened on both TVs. (I should add that it all worked fine when I used a Samsung Blu-ray player as the DMP.)

After floundering about for a bit, I finally installed and enabled version 6.0.33 of the TwonkyMedia plug-in. This enabled me to play the video on the TVs, but with poor quality -- lots of tearing and jerkiness. Plus, it took an excruciatingly long time for the TVs to find the TwonkyMedia server. (Again, everything was ducky with the Samsung Blu-ray player in the loop.) The TVs have the latest firmware installed. Is there anything I can do to fix these problems?

One other, much lesser complaint: TwonkyMedia does not automatically unsqueeze 1440 x 1080 HDV video to 16:9.

Thanks in advance for any assistance.

For the final point - Twonky doesn't (by default) do any transcoding, which is what would be required. It is up to the TV to correctly support the aspect ratio information in the file being streamed.
No longer running Twonky

Thanks. The Samsung Blu-ray player doesn't handle the aspect ratio properly, either. Windows Media Player, on the other hand, does. I can deal with that, though; it's the basic streaming problems that I really need a fix for.

Update: Installed version 6.0.34, which solved the problems with slow Twonky detection and anamorphic unsqueezing. The basic quality problem (tearing, jerkiness) remains, however.
