Please help me understand what a DVR can do. I want to record shows in the city and take it out to the country where I have no TV reception and watch them out there. If that can be done then:
How many DVR;s do I need?
Do I need a special TV?
I know this may seem basic but I am not really tech savvy.

Given the limited information you have provided, an answer is not possible. Who is the cable provider in your main residence? What type of DVR do they use? Many DVRs will not initialize unless they are able to access the cable network they are assigned to, so it is likely that it may not work at your other residence.

Well, DVRs cover a pretty broad spectrum of devices, including PCs that have had DVR capability added with a tuner card.
DVRs from the cable company have full access to everything your cable account has access to, at full quality. However, as mentioned before - many of these will refuse to even boot if they don't have a connection to the cable network. They implement Digital Rights Management (DRM - sometimes called Digital Restrictions Management, which is a more appropriate name) to make sure it is not possible to copy the contents to a hard drive or other machine.
Standalone DVRs (such as TiVo) tend to be more flexible in terms of operating without input, but still apply DRM to most recordings. Sometimes they are not able to access all content available on your cable network. Some of these MIGHT allow archiving of some content to DVD or an external hard drive for playback on another device, but most likely - you'd have to haul the whole box with you.
PC-based DVRs tend to be the most flexible, but also the hardest to use. These rely on adding a TV tuner to a PC.
Windows Media Center Edition can, in some cases, access encrypted cable content. However, as I understand it, this can only be done if you purchase the DVR solution with the PC itself. Blame CableLabs' insane restrictions for this.
Other packages like SageTV can only access the following:
Unencrypted digital signals (OTA broadcast TV via antenna, or unencrypted cable, which is usually limited to the major broadcast networks) - This is the digital component of Hauppauge's WinTV-HVR devices
Recordings of the analog output of a cable or satellite box using a video capture/compression device (Such as the analog portions of Hauppauge's WinTV-HVR devices). This usually limits quality to standard definition, the only exception I know of is the Hauppauge HD-PVR 1212 which can record component video signals in high definition.
Often packages like SageTV do not apply DRM to their recordings, allowing you to copy them to an external hard drive or another PC, so for example you could watch recordings on a laptop.
In my case, I have an old Hauppauge WinTV-PVR 500 for analog recordings off of my cable box, and a SiliconDust HDHomeRun for digital recordings of network TV off of my cable system.

The way it sounds... just like your post says.... you need a recorder.... Digital recorder would be nice too...
1) old school vcr/cd recorder might be your best bet.... that will play anywhere.... and you could dub the vcr tape onto the CD.... or...
2) a dvr used for video camera security recordings might work too.... Im not sure since i really have never tried to use one for this application but there is a basic video input and out put to monitor..(some type of balun or converter might be needed for the correct signal type)... 1 and 2 terabyte hard drives are available... and the run about 600.00 to start... again, more confirmation and research might be needed if you wish to record digitaly...
Bottom line, if your not timing your recordings around the enviroment of what a DVR can do, do it with the easier and less expensive VCR/CD unit.

#2 wont work at all, even if you could finagle a connector; you could only record analog video at SD, since the hardware must supprt HDMI handshakes and be able to decode the HD encoded signal.

Anything is possible.... converters do exist...
An oversite on my part is the lack of audio in the Security DVR... it just video....
Lets all remember. keep it simple for those who want it simple....
