I think I made the right choice getting the AKAI AD163X HD set top box. It saves to both Fat32 and NTSC formatted usb devices, and the format used is .ts which I'm familiar with (and can be played/edited on my PC). Not only that, but it will play the .mpg files recorded on the Strong SD set top box (but not vice versa). The EPG on it is pretty good and it's very easy to modify a recording schedule (it will also record digital radio as well) and there doesn't seem to be a limit on how many schedules one can have.
This was pretty much what I wanted, something that I could record HD with and be transferable later on. The DVD player is a bonus. That only seems to lack a memory function (which starts you at the position you were at on a DVD when you cut the power). That being the case, I'll move this one into the lounge, move the SD set top box with the hard did=sk in it into my bedroom and keep the Strong STB as a spare.
Why am I bothering? Well for the last two years Kevin has been running something called MythTV on a spare PC hooked up to digital tuners. It's very good because it uses an online program database that in general is kept up to date. Using this system one could find a listing for say, House, and set up a recording schedule for it. But you can set it up so that any episodes of House on any channel is recorded, or any episodes on one channel - which meant that last minute changes to program didn't screw up one's recordings.
All that will be gone once they move out.
I could try setting up something like this myself, but as MythTV is still in the beta stage and runs under Linux, it would require a level of expertise that I don't quite have (but which Kevin does). That being the case, having multiple STBs that I can record from will probably cover most contingencies. Of late I haven't been watching a lot of recorded (or even live) TV, but when I do I prefer to watch it when I want to, rather than when it's broadcast.
