Helix Internet & Illico TV?

Is this possible? Could we split the coax cable and run it into the gateway and modem and then use the former for the internet and the latter for the TV?

I ask because there are some limitations w/ Helix TV that are deal-breakers for me:

• Inability to record a TV program from when you started to watch it vs when you started recording it
• The delay between changing the channels

I have confirmed that these issues are not present with Bell.

Are there other limitations others have come across after using Helix for some time that they had wished they knew about before?

It is also disappointing that there are not more apps (E.g. Plex)
