	The problems arise when trying to record digital television. In general, most, if not all cable companies encrypt their digital tv signals. Since they undoubtedly keep their encryption techniques a secret, LMCE will be unable to decrypt those signals. The net result is that digital cable from a provider is unable to be tuned/recorded by LMCE, even when using a digital (ATSC) tuner. The only exceptions are the free, OTA channels. These channels are not encrypted, thus your ATSC computer tuner will be able to watch these streams. There are work arounds to recording digital subscriptions, but that will be added later as it is very cumbersome and unreliable.		The problems arise when trying to record digital television.

	Now, onto business. The ability of your computer's tv tuner will be limited by the type of signal. If you have an analog cable subscription, LMCE will be able to tune every single channel which you enjoy on your normal television. You will need an NTSC capable tuner for your computer.

	'''Encrypted signal''': If a piece of data is encrypted, that means that the information is sent in code which only a few people are allowed to know. Cable companies often encrypt their cable signal in order to prevent stealing. If the signal cannot be decrypted, the tv signal is not viewable.

	'''OTA''': This is shorthand for "Over the Air". This refers to any tv channels which are broadcast for free. They are over the air in the sense that all you need is an antenna plugged into your tv to access them. There is no need for a subscription to a cable company in order to receive these stations. However, some cable companies provide these channels in their tv line up.		'''OTA''': This is shorthand for "Over the Air". This refers to any tv channels which are broadcast for free.

All OTA stations will be required by federal law to cease broadcasting analog and begin broadcasting digital. That means that the free stations which are tuned using rabbit ears will no longer carry an analog signal. They will carry digital. Thus, a digital tuner will be needed to understand this new stream of data.
