fix: the responses to several requests returns erroneous values

[FelixPetriconi]

The comparison of the several responses with DLNA complaint servers has shown differences and were fixed accordingly

Please bare with me but I don't know much about C# or the used frameworks. Please advise how to improve the code if necessary.

I just can tell that now my Panasonic Blu-Ray player is able to connect to the Jellyfin instance.
The display of photos, streaming of mp3 and flac, and some mpg works fine.
I intent to add a working profile for that player as soon as I have found out how to get .mkv container playing.

Tried today the updates and now the Panasonic DMR-BCT750/755 is able to connect to JellyFin and plays videos back.

Which profile did you use? What kind of videos container did you play back?

I don't see how this would work as the response isn't being set to anything.

I cannot give you an answer to this, because I don't much about the used framework. I only can say that a response that is set to any mime type is a) not been accepted by the Panasonic player and b) it has now with this changes same result as with e.g. Emby 4.8.10 and Twonky Server 8.5.2.
I checked it on protocol level with Wireshark.

What kind of profile do you mean? Device profile?
If device profile, Jellyfin tells me in the log, that the default profile is selected.

Test was done MP4 with H264/AAC.

Well, before this patch, the Panasonic would just throw the error "Unable to connect to server".
With this patch, it just works.

[FelixPetriconi]

The same for me now.

Applied the changes, recompiled and replaced the DLLs and the Panasonic can still access JellyFin.
