    @abu baniaz, with reguards to OpenTV zapper do you think it could be ported to openatv, I use epg refresh I select a few channels only for freeview bbc one and E4 but with reguards to IEPG data 1 when I select that in epgrefresh obviously no signal as to speak in autobouqets maker I don't want to have bouquet sky info shown and in epg main setting i have nothing enabled
    I know I can just select a channel on freeview and epg will be pulled in but would be good to have epg there without having to zap to a channel if possible

    You will have to ask ATV, but it is just a zapper. You can select iepg from service list instead of bouquet.

    I'm wondering if it's some weird bug that's specific to Zgemma or to the Zgemma H7.
    Definitely causes an issue (sometimes!). I can't pin it down. I know if I don't disturb the download, then I have no issues with the EPG.

    So this huffman issue only happens when a user zapperdy zap zap zaps on multi-tuner box... eg. zapping tuner 1 while opentv zapper has also initiated an epg download on tuner 2?

    Yep - I think that about describes the error situation - zapping while the OpenTVzapper is running seems to trigger the runaway error messages. It would be great if a code change could be made. Happy to test.

    I have submitted a pull request here: https://github.com/OpenViX/enigma2/pull/849
    A build will need to be run for it to be tested

    Waiting on dev build 6.3.004.013 - the 011 and 012 builds did not work for me as there was a bug in menu.py which surfaced in my sorted menu. I did run the 012 build for a couple of days unattended on my single tuner HD61and the scheduled run of OpenTVzapper worked fine, but I didn't try to provoke the huffman error. Once 013 is available I will download later tonight on my Quad Plus and test.

    Dev build 013 does not seem to have completed for ax61HD. I did flash the 013 build for the QuadPlus early this morning and will test it.

    Dev build 014 has completed for the AX61HD. Have downloaded and flashed ok. Looks good so far. My AX61HD has only a single DVB-S tuner, so can't verify huffman issue on it. I am testing that on the Quad Plus.

    Dev build 014 for Quad Plus tested for the "huffman error" bug. I can't provoke the runaway log error, despite switching DVB-S and DVB-T channels and starting recordings etc. while the OpenTVZapper is running. Problem seems fixed on the development/test image. Should be good for Release. Thanks @LraiZer and @abu baniaz!

    I just built myself a 6.3.004.015 developer image for my Zgemma H7S and I too am unable to provoke it into showing blank EPG entries by doing things like channel zapping while OpenTV EPG download is occurring.

    This is most excellent news.

    Thank you @LraiZer.
