Problems with uVerse DVR connected to a network switch and 1x3 HDMI switch

Question

So that I can connect multiple devices (Apple TV & BluRay player), I've connected my uVerse DVR to a network switch with IP Quality of Service function.  Is it known whether or not this will cause problems?  I am having problems, but see next question for probable cause. I have also connected my HD TV to a 1x3 HDMI switch output, with inputs from the uVerse DVR, Apple TV, & BluRay player.  This clearly has caused problems because the DVR goes through the power on sequence almost everytime the TV is turned on, I have intermittent problems with the HDMI switch displaying video on the TV, and on several occassions, shows scheduled for recording haven't recorded at all or only partially recorded.

I've been having problems with this for months especially with the GigaPower rollout and broke down and decided to resort to some network engineering tactics versus calling out AT&T Techs. The Techs are good at their job but they are only knowledgeable about the hardware aspect but are dumb founded on this one and it's not their job to know.  To the point of using a switch next to the DVR and this counts truly for all set top boxes via Ethernet they need to be physically seperated wires. Well, unless you want to pay someone to put an extra Ethernet drop next to each wired set-top box or DVR this isn't feasible so options are deal with it or spend $20 more dollars on a switch that supports 802.1q trunking which makes two 'virtual' independent ethernet cables over one line.  If you can do it great otherwise this takes a higher than average knowledge of basic networking.   A basic setup would be: + Get two switches - Netgear GS108T or GS108E I've found does the job well. + Enable 802.1q advanced VLANs+ Make two additional vlans 2 and 3 (1 is the native VLAN)+ Mark a port as tagged 'T' for the trunk port to the other switch for VLANS 1,2,3 (I used port 8)+ Assign VLAN 2 and mark as untagged for ports 2-7 - this is for data traffic+ Assign VLAN 3 and mark as untagged for port 8 only - this is for video multi-cast traffic+ ***DISABLE*** MULTI-CAST IGMP SNOPING otherwise IPTV won't work. On the back of the Uvserse router, take an Ethernet wire and plug into port 8 and take an Ethernet cable and plug into port 7.  This does not create a loop though sounds like it, we've created two unique layer 2 networks.  Now configure the second Netgear switch (or switch of your choosing...) the same exact way but plug your DVR into port '8' and all your data stuff XBox, whatever... into ports 2-7. Whalla, you've eliminating multi-cast flooding and DVR traffic is independent.  Ever since I started doing this I increased the speed throughput from 10 MB/s or to never working to a full reliable gigabit speed or respectibly whatever UVerse service you get.
