A:Answer For recording a full TV program, a Blu-ray Disc is recommended, as it can hold significantly more data, up to 25 GB, so depending on the type of DVD and its capacity, you might be able to use the LG 8x External USB 2.0 Blu-ray Disc Double-Layer DVD±RW/CD-RW Disc Rewriter - Black, Model # BP50NB40, to record a TV program onto a Blu-ray disc if you could connect it to your TV, but the drive only connectes via USB so you will not be able to record from your TV. Some DVDs and CDs do not have enough capacity to record a full TV program, and are not suitable for recording full TV programs due to their limited storage capacities, so you will need a hard disc drive with enough capacity.
The easiest way to record cable TV shows is by using a PVR (Personal Video Recorder) option built into your TV, which allows you to record shows directly onto your TV’s hard drive.
If you have a TV with built-in recording capabilities, you can set it to record live TV to an external hard drive.
A single-layer DVD can store 4.7GB of data, which is about 120 minutes of standard definition video. A dual-layer DVD can store 8.5GB or about 240 minutes of video. However, the actual video playback time a DVD can store depends on video quality, compression, and encoding method.
A single-layer Blu-ray disc can hold up to 25GB, and if you go for a BDXL disc, you can store between 100GB and 128GB, making them perfect for large data backups or high definition videos...^Ivan.
