BEWARE...
from the page on walmart.com describing this recorder, it does not appear to have a tv tuner of any kind.
So you cannot connect it to your coax cable or antenna.
You can only connect it to a cable box with a composite or svideo output and record that.
Note that the FCC required newly shipped devices on Mar 1 2007 that have an analog (NTSC) tuner to also have a digital tuner. Thus to save money many companies are dropping the analog tuner so they dont have to add a digital tuner.
