Which fire tv model and firmware bug are you referring to?
Please see here re Erics response:
I understand the transcoder issue, but I would like to know what FireTV device you are using and why you need an always transcode option.
If i dont transcode the video the image quality for the main HD tv channels (1080i) (bbc, itv, channel 4) is horrific and virtually unwatchable.
The hardware deinterlacing does not work and whenever there is fast moving motion the picture breaks up in interlaced lines.
The app also does not switch framerate / resolution so everything is delivered in 1080p even though the non transcoded stream is 1080i
Basically forcing 720p 6mb and using old transcoder fixes all issues and plays back ok at the stuck 1080p with no artefacts (except for audio sync issues occasionally)
Using new transcoder works some times until it decides not to transcode and the all the interlacing issues return.
Regardless of source / transcoder etc, the app never switches from 1080p 60hz (even though 50hz is default here in uk)
Hope that helps
Which fire tv model are you using?
FireTv 4k stick
(I.e the one that used to crash when playing 1080i)
Now it seems to switch to software (or no) deinterlacing instead of crashing, which is unwatchable for medium to fast motion on screen
Watching something like F1 racing is lots of interlaced lines everywhere and looks terrible
When transcoded at 720p - perfect
@timellert If you still have one of these F1 recordings with lots of interlacing artifacts, could you send the video to [email protected]? I just got a new Fire TV 4k Stick and would like to replicate what you're seeing.
Sure, i dont have any previous recordings but will send over the next one this coming saturday
I’ll even take Free Practice 1.
Sadly we only get quali and the main gp on channel 4 here!
I will try recording the football instead tonight to see if that has the same issues and send over tomorrow if it does
hey Eric.. some recordings winging their way to you via email... all have massive interlacing artefacts when played at normal res on fireTv 4k via channels... especially the F1 quali which is mainly a blur of interlaced lines
This is great. I was totally able to see what you're talking about. We'll figure out what the best steps forward are for this.
As a follow-up to this work, I've just released a new experimental setting to provide automatic bandwidth adjustment for Live TV watching. You can read about it here:
Running 2019.12.26.0206 currently (update about once a week)
I have a remote (liveTV) stream that is choppy. Is this due to the new transcoder option?
My remote site (AppleTV) is set to 720p @ 3mbps
My remote site has 100mbps download
My local site has 200mbps download/20mbps upload
My DVR server is running in a Virtualbox which has 4 cores (AMD Ryzen 2400G) and 4GB dedicated to it.

Since the errors all look to be about problems with PTS in the stream, it looks like the problem was most likely with errors in the broadcast stream.
(Please correct me if I'm wrong.)
I’ve made some improvements to the latest DVR beta to hopefully fix what your seeing. Can you upgrade and try that?
Also, with this new system, if it’s working correctly you should be able to keep your streaming quality at 8mbps and the client will adjust up and down based on how much available bandwidth it sees.
Could you see if it handles everything correctly after you’ve upgraded?
I have just upgraded. I'll try in a bit and report back...
