you cant as far as i know if you login with user/pw as epg when you log into your iptv provider is server based
but with m3u you can leave epg empty meaning no epg , but as i said i had cashes too untill i registred my mac adress on my provider and used the magportal adress
it might not work for you but it did for me
i had almost same issue until i registered the mac adress with my iptv subscriber so try and register your mac adress with yout iptv provider
i think it has something to do with epg because if i didnt use epg it didnt crash for me
right finaly figured how to get vod filter and search to work 
first you have to register your mac id with your iptv subscriber , once you have done that you will get a mag portal adress if you use that adress vod filter and search will work.
kinda strange that you must register mac id with your iptv subscriber to make it work imo
yep i have done factory reset too
nope
i have even asked my isp provider and he has an z7+ and he has no problem with same software/firmware as i have and tried bypass my router also with no success
so sorry i got no clue what is going on 
i had the same catchup issue but once i registered my mac at my service provider it worked
vod filters or search dont work on my z7+
search find nothing for me and on filter i can only select the sort order which dont sort anything and i know this isnt a provider isssue because vod works on any other app like iptv extreme so would be nice if someone has a solution for this
