It's also important to note that cable companies can change their encryption status when they please, so while your channels may be unencrypted today they might not be tomorrow. Alternatively, you can contact your local cable company, but that may prove to be a frustrating experience. To check if your channels are provided in the clear via QAM, you must attempt to tune them either with a QAM tuner card in a PC, or with a newer television set that has a built in QAM tuner.

Additionally, the native numbering system for QAM tuning differs from that of the lineup providers (see Adding Digital Cable Channels (For ATSC/QAM Tuner Cards - USA/Canada)

The only exception is the free to air (FTA) high definiton channels (such as ABC, CBS, NBC, etc.) that cable companies by law must provide in the clear, though that's hardly a consolation as these channels are provided for free over the air via the ATSC standard. Unfortunately, QAM channels are almost always provided encrypted, so this method does not work for most.

This method is the most reliable means of recording digital cable, assuming your QAM channels are not encrypted, as it does not rely on any outside hardware from the cable company which avoids the support problems of FireWire set top boxes as stated below. They support both standard definition digital television and high definition digital television. These cards simply 'download' the digital video streams straight from the cable to your hard drive in their original form, hence preserving their original quality. These streams, if unencrypted, can be tuned via a QAM tuner card. In the US, digital cable is generally transmitted via quadrature amplitude modulation or QAM, a means of transmitting digital data such as digital video streams. A method for changing channels on the cable box ( IR Blaster or firewire - Note: Recent versions of the HD-PVR now include an IRBlaster that is supported by the latest drivers.A cable box that supports component video out.The Bottom Line: Necessary Equipment and Services Judging by the mailing list, this has become one of the most popular options. It is fully supported in Linux, and can provide MythTV users a way to record all of their digital HD content with negligible quality loss, regardless of encryption status, when paired with a cable or satellite company provided tuner or STB. The box is capable of encoding 480i, 480p, 720i, 720p, and 1080i component video into h.264 video with a hardware based encoder. Hauppauge has released the Hauppauge HD-PVR, a high definition component capture box. Read on for a breakdown of these three options. The only option that works regardless of encryption status is the analog tuner card option, but this method does not preserve the digital quality of the incoming video and hence can produce serious degradation of the quality of the video depending on a number of factors. These two options are to use a QAM tuner card to tune the digital channels or to use FireWire output from a cable company provided cable box, and they are the sole means of viewing digital cable channels in their unaltered digital form, as well as the only means to receive high definition television provided through digital cable. To that end, two of the three options for recording digital cable solely depend on the encryption status of your cable service. In practice, however, recording digital cable is more complex due to industry imposed encryption cable companies often encrypt the channels provided via their cable service such that only rented set top boxes (or other means such as CableCARD) are capable of receiving and 'descrambling' the channels for viewing. Instead, the digital stream is simply 'downloaded' as is in the form of a transport stream. Recording digital cable versus analog cable should, in theory, be a simpler matter than recording its analog counterpart, due to the fact that unlike analog television, digital television need not undergo analog to digital conversion and encoding to be digitally stored on a computer.
