I need to clarify some questions

Hello WG++ Devs and community,

Before going deep into the subject here are the specs of the setup :

WebGrab+Plus V1.1.1 and patch exe V1.57.0
Windows 10 Pro

My current EPG is working while using "horizon.tv.fr.ini" and "horizon.tv.fr.channels.xml"

I want to speed it up a bit, is it possible ? (without being IP blacklisted by the way ..) for grabbing about 200 channels on 7 days, my computer takes about 5 hours to complete the task. My Internet speed is 250Mb down and 25Mb Up
I tried also to run WG++ into my own computer to check the speed and it's the same

I live in Switzerland, and I want to grab some Italian channels, but as far I've tested, currently using "laguidatv.it" it do not work.
I am wondering if this is because I need to request a newer ini file, or the website is blocking other IP address which is not italian ?
I tried to browse the website and it load successfully, so I guess it's not geo-blocked, but those it depends on an API or what ever ?

My setup is made on top of Proxmox VE
Intel Core i7 - 6700K 4GHz
32 GB of RAM
500 GB Samsung SSD EVO Basic

3 VM's
VM 1 : shares 4 USB DVB-T tuner inside, tvheadend installed as "master" because the lan traffic is routed trough this VM even for Satellites channels
VM 2 : shares 4 PCI-e DVB-S2 Quad-Tuner, tvheadend installed as "slave"
VM 3 : Windows 10 Pro which is used to generate the guide.xml file every day at 00:30 to finnish more or less it's task 5 hours later

You'll find the required files in the attached zip file,
Many thanks
