    Default Transcode problem Panasonic Viera

    A few days ago I decided to use Mezzmo instead of some free alternatives because they could not deliver the correct aspect ratio. Now I have another problem, the transcoding is super slow.

    My tv is of model Panasonic TX-P50G30Y. My computer is running AMD Athlon Dual Core 2.61 GHz with 2 GB RAM. I know this computer is not very fast but I did not have this problem when I was using Serviio. Now the fps is between 8 and 18 fps so I have to pre-transcode. But even then it takes a ridiculously long time transcoding the video. The device profile I use is called 'Panasonic Viera (2011 models)' but I have tried other Panasonic profiles as well. I am still using the trial version of Mezzmo but I decided to buy it just before this problem occured. If there is a good fix for this problem I will buy this software immediately otherwise I might hesitate. (Probably I would buy it anyway because of the pre-transcode option which is the best. In my opinion it is worth waiting a few hours to get the correct aspect ratio).

    I have seen other similar posts where they added FFmpeg Information so here is mine.
