Consumers often ask why it's that DVD recorders with difficult dr functionality tend not to have twin electronic tuners, a feature that would allow them to watch one particular electronic channel and record a different a single. The reason for your omission of this helpful option is explained in this two-part series.
The explanation for your lack of twin electronic tuners in DVD recorders with very difficult gain capability is much more complex than you may possibly imagine. To begin with, you have to accept that in these machines, anything recorded towards the tough disk has to be excellent enough for recording onto a DVD disk in a fraction from the time it takes to watch the programme.
So why is this?
This is since consumers are utilized to CD recorders and DVD recorders that can record much faster than the playback time, and a DVD recorder that could not do this would be labelled as "slow" and would probably not be commercially viable simply because of this.
So what has the DVD recording speed to do with dual tuner functionality?
Properly, this is where things get complicated. I've explained that consumers will need DVDs to be recorded faster than "live" playback time. To achieve this, any recordings on the difficult disks of DVD recorders with tough drs; i.e. any recording that a shopper may select to record to DVD disk at any moment; has to be already in DVD top quality and format. The problem is that a few of the Freeview channels do not broadcast in very good enough excellent for DVD disks.
This means that these Freeview signals must be converted to DVD excellent as they're written to your challenging disk of your machine, just in case a you select to record the programme to a DVD disk later. The conversion process takes as lengthy as watching the programme. Since it's done within the background as the programme is broadcast, you do not notice any delay. After the programme has ended, you have it in DVD excellent on the HDD difficult disk, which means it's ready for recording to DVD later on the expected faster-than-live speed.
So now we have explained the reason that any recording towards the very difficult disk has to be converted into DVD excellent. In component two of this series we will discover why this conversion process would be the reason that almost all DVD recorders with very difficult generate functionality do not have twin electronic tuners.
