I Don't Want X1

Really old stereo system you have there - S-video and component video disappeared 10 yrs ago or more. When Comcast forced the switch from analog to digital years back (2009?) they instantly made all stereos and DVD/VHS recorders obsolete - at the time I had a really sweet Yamaha stereo with a legit power output of 100W for a 5.1 system, used S-video and digital co-ax to feed A/V from my STB to stereo, then output the video to my TV with S-video (don't need to talk about my DVD recorder setup for the purpose of this post). When they went to all digital I had to buy a new plasma HDTV and an HDMI compatible stereo, a Sony STR-DH720, which has 3 HDMI inputs and one output, which goes to the TV. My A/V equipment is in an antique armoire, which is pretty cramped (can only fit a 43" TV in it), components are on shelves, but the back of the stereo is hard to get to because I didn't leave enough slack in some of the speaker wires I ran when I upgraded to a 7.1 speaker system - so no way I was going to mess with component video and analog 2.0 RCA audio - all the cables I had were only 6' long and too short to hide behind the armoire. Plus HDMI is SO MUCH easier than anything else it just made sense to go all HDMI.

My suggestion would be to upgrade your stereo and buy a new DVD/VHS combo unit - actually, scratch that suggestion - after checking online, the last combo unit was made in 2016, all you can buy now are used ones, and their cost is astronomical, so you're stuck with the one you have now. I was going to suggest using an HDMI splitter and a HDMI to S-video A/V converter along with a new stereo, but after checking I see hardly anyone makes stereos with component in/out anymore - one that does is the Sony STR-AN1000 7.2 Channel Home Theater 8K A/V Receiver, will cost you $700 plus tax, the splitter would cost you $22, the converter $25, so for ~ $800 you could compensate for an X1 box's lack of outputs. That's an expensive solution, but the only one that will work if you're forced to get an X1 box someday - as far as your VCR, when it dies you're SOL - I suggest you try to find an buy a VERY slightly used combo unit now and after testing it stash it in someplace safe, because when your VCR dies you will not be able to replace it. When that happens you have no choice but to send out your VHS tapes to be digitized and copied to DVDs, although some vendors may refuse to convert VHS tapes of movies you bought because of copyright issues - or you could find a cheap used VCR on eBay, buy a VHS to DVD converter, and do it yourself, but my god that would take an enormous amount of time because a 2 hour movie would take 2 hours of computer time to convert - if you have dozens of VHS tapes you could spend weeks doing that - still cheaper than shipping them out for conversion at $25/tape. Oh, and you have to have a DVD writer on your PC - many new PCs don't have them, so you might have to buy a USB DVD drive too, and you'll need to buy a DVD player to watch the converted tapes, but luckily they're cheap - you can get one that has an HDMI output that upscales SD to 1080 for about $40.

Your real problem here is wanting to watch old VHS tapes with any combo of stereo/TV/DVR/STB - gonna have to bite the bullet and digitize those tapes sooner or later, because at some point in the future even used VCRs won't be available. I almost want to say your biggest mistake was not buying a VCR/DVD player before they became totally obsolete, but you didn't have any way of knowing they would cease to exist someday.

@SammyFL​ "If they could simply allow the promo plans to work with the older DCX boxes, then there wouldn't be an issue." Except for the refunds given and promised by tier 2 when I return my XG1v4, Comcast almost never does anything to benefit the customers as far as service or pricing. I'm still angry that they reduced all the regular broadcast content from 1080 resolution to 720, starting in summer 2016 in some places, and February 2017 in my area, except for the local broadcast channels, which took them until January 2020 to down convert those. I guess you watch them in their original format I switched to an antenna, but it's a bit of a hassle and then you don't have the immediate ability to pause or go back in the buffer unless you switch back to the DVR.
