We've been pretty happy with TWC. We've got a Scientific Atlanta 8300HD DVR which is "OK" - I think it's a Pioneer unit. We receive approximately 98 SD cable channels, 35 digital channels (a big improvement over SD - most likely still 480i), ~40 digital Music Choice audio channels (awesome sound), and 6 HD channels.
We pay just under $80 a month for this service, which includes Road Runner high speed internet (it's running around 2 Mbps).
I think it's a decent value, seeing how we have 3 tv sets upstairs, 2 on the main level, and 1 on the lower level. I can't imagine the cost to rent 6 satellite receivers. Sure, we don't get HD or digital channels on 5 sets, but it would only run us $6 a month to get a DVR for each additional room. It's month to month, and the price is guaranteed through 2007.
Our DVR sometimes freezes up, like a computer does. All we do is reboot the system, and it's fine. We find switching through the DTV or HD channels too quickly will cause this freeze up to occur. I've called TWC out to check the DVR. They were out within a day, and had 5 new units to test. Amazing service - no charge. We found out it's not the DVR's (they all suffer from freeze up once in a while). We just need to change channels a bit slower on DTV/HD - no big deal - patience.
The one qualm I have against TWC is the lack of ABC HD. I'm not sure what the beef is with ABC, but I missed out on a lot of college bowl action in HD. I absolutely love Discovery HD. I'm sick of TNT's Law and Order, but was pleasantly surprised to see Remember The Titans this week.
As far as customer service, I rank TWC right up there with Wide Open West - almost perfect. We have two competing cable companies in Columbus, and they constantly fight for our business. A week doesn't go by without an ad for either provider. It makes it nice when our contract comes up, and we just bargain for whoever has the better deal. SD cable looks better with WOW, but I'm thrilled with DTV and HD with TWC.
I can't even imagine calling a dish type network up for service. This is way too easy.
