I know I can't change the external DNS on the router due to the IPTV, but I'm having major slowness related to the uverse dns. When I run full DHCP on my laptop the internet lags, but when I change my DNS to opendns everything loads instantly. Is this a known issue? Any way to fix this other than set per laptop? I have a Mac Server on my network that I could setup as a DHCP server, just trying to figure out what's wrong with the uverse dns.

The U-Verse RG has a known issue with slow DNS lookups. Using OpenDNS is a great workaround, but requires entering the OpenDNS entries on each computer individually.

The need to use their DNS for the iptv makes sense, but they should allow us to change the dns that is used with the dhcp scope for all computers in the house. They give the option to turn off dhcp, so i might just setup my own dhcp server...
The STBs use DHCP to configure themselves. If you set up your own DHCP server, you will need to specially program it so that the information handed out to the STBs is identical to what the RG would give them.
Alternatively, you can put your own router into the network and put your computers behind that router. That way you can program your own router to hand out any DNS you want to your computers, and the STBs will remain connected to the RG and get their DHCP info from there.

If you wanted to you could, in theory, set up your own DHCP server and use the Moto/Cisco (depending on brand of STBs used) MAC OUI/vendorclass to give different information via DHCP than your other hosts...
Edit: Guess I basically just restated what SomeJoe said, but it should work just fine either way.

I work from home and am on the internet about 12 hours a day for work. I have noticed that about half of noncached dns lookups are timed out/404. This to me is not an acceptable success/fail rate. It would be great to see this at the top of the bug list.
According to dnsguy at dslreports.com, it is the 2wire RG w/dns problems. A good work around is to
hard code the ATT DNS servers in your connections wired/wireless in the lower right corner of your
Windows taskbar (could also go in through Network Connections, right click on the connection,
Double click the wired (do the wireless one next if installed and active) connection, click 'properties',
double click 'internet protocol (TCP/IP)', leave 'obtain IP address' alone. chose 'use the following dns
servers' , plug in 220.127.116.11 and then 18.104.22.168, then click 'ok', then 'ok' again and 'close'.
For good measure bring up a command prompt and run 'ipconfig /flushdns' then press 'enter', you
should be good to go w/o any page load or graphic load problems or 'looking up...' waiting times.
I had tried openDNS, but ended up having these same problems and went back to ATT DNS servers
and have had no problems since then.
