It all depends on the channel mapping, and what your Cisco DA is actually displaying.
For some unknown reason, some of my local channels map to the SD feed that is being sent, and how that SD feed is being sent.
If you were using an old CRT set, with the cable plugged right into the set, and got black bars on top and bottom, that is a letter boxed 4:3 SD feed. My guess is that your DA is showing the letterboxed SD feed. If you are now using a DA on a HDTV set, and are tuning to this channel, you will get the postage stamp, because your TV thinks its a 4:3 signal.
On my system, Fox 5 from NYC is delivered letterboxed on Channel 5. If I use my Digital Adapter on my HD set, I will get a postage stamp. If I used the cable right into the back of the TV, I wil get three versions of Fox 5. Analog on Channel 5, a digital SD version on some nameless channel (93-5 or something like that), and a HDTV feed on 5-1 (Obviously making use of QAM / PSIP). If I use the Digital Adapter, and select channel 5, it provides the letterboxed version in SD (postage stamp). Ironically, if I choose ESPN (Channel 21), I get the HD feed, and it is displayed proper full screen. (But would be letterboxed using the TV's internal tuner for channel 21.)
If you hold down "7" on your Cisco Remote, you will bring up the troubleshooting menu for the adapter. You can look at the channel maps, and if you scroll to the channels of interest, you will observe that the MSG and SNY feeds that are being displayed postage stamp are actually letter-boxed (top and bottom black bars) SD feeds being displayed 4:3 on a HDTV, which is adding the side bars.
I would hope that when TWC finally pulls the plug on analog they will drop all redundant SD feeds. This would eliminate most problems. There will be issues forever going forward if a channel is only provided in 4:3 SD, and is provided letterboxed. You will need to make a screen adjustment to get that picture in full frame.
So yes.... Your observations are not uncommon....
TWC needs to eliminate redundant SD feeds and fix their mappings.
