Upgrade from XG2v2-P to XG1V4

Ive upgraded with a 4k tv.  I’ve tried to order the XG1V4 through customer service.  They are adamant that all I need is an Xi6, and they keep sending them.  I lease a Comcast modem so no issue there.  I’ll refrain from returning these 3 extra boxes until I hear.  Could you please advise on the best setup to take advantage of 4k as of July 2026.  As for the DVR the XG2 is cloud based, it’s ok but I prefer the hard drive.  The cloud based one gets confused and sends it back to the start with no way to return to the spot I lost it.  Does the XG1V4 still have a hard drive as of July 2026?
