Hi justme28...........
Hopefully most of your questions have been answered, but we need you ask you a question...............
Why do you think you want a new STB ?
The only reason to get a STB is if you want to watch "Digital" TV, which comes in two flavours, Standard Definition (SD) and High Definition (HD).
Honestly, without taking a poll, I'd guess that 99% of the regulars around here wouldn't recommend you actually go and get a STB just because you want one.
However, If you really were after a PVR, that's a different kettle of fish .............
As much as I love my Toshiba HDD-J35 ( Toshi J35) unless you were planning on upgrading your TV in the next year or so, you may be better off going for a real cheap "E-Bay Special" PVR.
Have a think about what you want and want to do and let us know a bit more about what you want and I know you'll get bombarded with heaps of information
