HD recordings take up significantly more hard drive space. for example, on a DVR with a 250gb hard drive, you can record 250 hours of SD programming or only 30 hours of HD programming.
...Does anyone know if recording programs in HD reduces the availabe recording time on these hard disc devices? Here in NY, I have the option of recording the same program in either SD or HD. As I'm away from my DVR the whole week, things seem to be getting filled up when I record most of the programing in HD.
Just wiondering if I could get more recording time by dropping down to SD.
Any ideas?
