It is not a PVR. It's only a receiver. http://www.saortv.info/terrestrial-s...iew-reception/
Almost none of the receivers that take external HDD or USB memory Stick are "proper" PVRs (i.e. dual Tuners, internal Drive, Series Link, MHEG5).
IMO you need Dual Tuners and MHEG5 for a proper PVR. If the TV has DTT (Compatible with Irish Digital even if not Saorview Certified), then like VHS you only need one tuner and could perhaps use external HDD. An External HDD is a much less reliable option than internal HDD in some cases.
Even in the single Tuner case you may need MHEG5 for series link. It's likely RTE will add an MHEG5 EPG with Series Link for PVRs. A Dual tuner gives ability to have overlapped recordings on more than one Mulitplex (There will be at least a 2nd Mux, and there are allocations for 6).
MHEG5 is mandatory part of spec
I'd recommend anyone really interested in PVR to wait till June/July. They may
then be able to record all UK FTA TV and Irish TV on a single dual tuner Satellite box/PVR. Also we should know what is needed for Series Link.
