Not sure if this helps but i had to install the drivers for wintv-dual version separately.

Perhaps check the drivers here: Hauppauge WinTV-quadHD (DVB-T/T2/C) - LinuxTVWiki

Thanks for the info Mario77, guess I’ll just have to be patient for RPi4 frontend interlaced support.

JanneK yup still haven't managed to fix this.

I also tried the Milhouse dev builds with Kodi 19 and still the same, RPi4 just doesn't render interlaced content well at all

Thanks again, but still same issue

I set all the settings you suggest in both kodi and tvheadend.

The judder goes away when disabling the deinterlace method but with it off the quality sucks.

Also after checking the tvheadend settings i noticed that although the default stream is pass kodi still switches to htsp. In fact with htsp disabled the stream wont even play.

Thanks guys,

Interestingly there is no 25hz option for 1080 and I tried just whitelisting 1080 at 50 but I still get the judder as the TV is switching to 1080p.

Is there anyway to force Kodi to use 1080i instead, maybe this would solve my issue?

chewitt I think i saw you are streaming tv from finland, thats where I’m based so would love to know your kodi and tvheadend setup.

I’m running everything on a pi 4 and just updated to latest libreelec 9.2.3 but still suffer from slight juddering on the tv stream.

I run kodi at 1080p 50hz and keep that resolution as the tv stream is 576p, I’ve tried so many settings on kodi but still get slight judder when using the full MMAL or BOB deinterlacing. Using half results in bad aliasing

I found using hw decoding and 1080p 50hz, full mmal deinterlacing gives ok results but still a slight judder for the live tv stream from tvheadend server DVB-C usb tuner.

My tv is a 55” 4k sony. Which looks fine with my old dvb-c digibox at 1080i.

cheers for the help.

Thanks Nicolas, tried all the settings and it definitely improved but still the 720x576 mpeg2 live tv video quality isn't great

Hopefully this will be improved in the future.

Thanks Nicolas, I will try the. whitelisting tonight. As of yet I hadn't tried that.

I did search the forums but didn't find any specific settings I should try with regards to this issue so many thanks for pointing these setting out.
I did find a pretty good guide on OSMC which should probably be the same for LibreELEC: [HowTo] Guide to the Kodi whitelist function and related settings - HowTo - OSMC Forums

Hi all,

I just setup my new RPi4 with the latest LibreELEC and it works great but my main use case is for Live TV to replace an old DVB-C cable box.

Got Tvheadend setup and working just fine however when playing the streams the interlacing and aliasing is pretty bad

I've tried all the settings but no real improvements with disabling MMAL HW acceleration, change the playback interlacing (bob, mmal half/full) etc.

Can anyone suggest anything else to try as its so close to being a perfect solution just the video quality is bad.

Thanks in advance for any help.
