depends whether you just want to record something to watch later or want to save it permanently.
A PVR (personal video recorder) with a twin tuner and hard disc will enable you to watch one channel and record another (sometimes 2 others depending on which mux the programmes are broadcast on). depending on the size of the hard drive you could get up to 200 hours or more stored on the hard drive, more than enough for normal use. These recorded programmes can then be transferred to either a DVD or VHS, depending on which format recorder you have.
Obviously, DVD will be better quality but if you already have a video recorder you might want to save some money at this stage. If your TV is getting on and the picture quality is poor you may want to upgrade but if the picture is good from your Sony digibox it probably won't be any better from a PVR.
Twin tuner PVR's can be bought for well under £200 now and will revolutionise the way you watch TV. You can instantly record and watch any time, pause live TV (great for when the phone goes) and loads more useful functions. For more information go to click here
