There are several scenarios for using an externa TV tuner box. The first is if the Tuner box has a coax output (for channel 3 or 4) and the TV can be tuned to that channel it can be used in place of the TVs internal tuner. An example is if the UHF tuner is out (channels 14-69) it can be used to receive those channels. If the TV tuners VHF (2-13) and UHF (14-69) are out and the TV has an AV input (yellow-white and or red) the TV tuner box can be used to receive the antenna channels. Similarly the TV tuner box can usually also be set to receive cable TV channels by changing a switch on the box or changing a setting in a setup screen on the TV tuner box. The second instance (and this will become more important as we near the FCC analog signal cutoff date of Feb 17, 2009). All analog signals will be cut off on that date. Older TVs that do not also have the ATSC or QAM tuners in them will not receive antenna or digital cable signals. Many TVs sold after around May 2006 to present have those tuners built in. Virtually all HDTVs sold after that time will have them. The TV tuner boxes are available now, but generally are in the $150.00 - $200.00 price range. As we get closer to January 2008 we will see more of these offered in the market and will likely be much less expensive $40.00 - $50.00 range. The Federal Government has a program for issuing $40.00 vouchers for such TV tuner boxes and each family will be alloted up to two. Many consumer electronics shops and stores will have the boxes and be able to redeem the vouchers.

It depends on the set you are watching on and your cable service. If you have a cable service that sends in all channels, digital and analog, without the need for a set top box, then you can get all the channels available if your DVR and television both have digital tuners built into them. If your DVR does not have a digital tuner, it will only be able to pick up the standard channels and not the "virtual" channels available through digital service (i.e. 8.1 or 17.4, etc.). If the DVR does have a digital tuner, but you are still watching on an old analog CRT television set, then you won't be able to watch the virtual channels while the DVR is recording, since the old TV won't pick up those in between channels. So, the answer is, if you have a set with a digital tuner, and a DVR with a digital tuner, you will be able to watch any channel while recording any other channel, as long as they are not encoded. If one of the two does not have a digital tuner, then your watching selection will be limited to what it can pick up.
Yes, you can operate two TVs from a Time Warner cable box by using a splitter. However, both TVs would need to display the same channel since the cable box can only output one signal at a time. Alternatively, you can use a second cable box if you want to watch different channels simultaneously on each TV.
