make sure you know what you are buying
os:
Windows Vistajust added this to my future proof system, to make it more future proof, but i am looking long term with this system, which is why i have bought a quad core cpu (nothing uses 4 cores yet!)8gb ram (same story!) vista 64 bit( how many apps are utilising this underrated o/s!!)and this tv card. if you uy now, you will only receive one HD channel in the uk..BBC hd..and that only runs for a few hours a day. there are more in the pipeline, from channel 4 and itv, but as yet, nothing else. all the other channels it finds are beeb1 beeb2 beeb 3 beeb4 itv1 and channel 4 THATS ALL FOLKS. apart from that, it does exactly what it's supposed to, and it works with vista 64 if you download the drivers from the hauppauge website, they don't come on the cd.
Re: Dual tuners do not need dual inputs
This is only correct in the case of DVB-T (Freeview), not DBX-S (satellite). Hence the comment is incorrect for this product.
With DVB-S the receiver "talks" to the LNB on the dish and selects one of 4 modes. This is why you get dual and quad LNBs, and why the Sky+ system requires two cables from the dish.
Modes are:
High Band + Vertical Polarisation.
High Band + Horizontal Polarisation.
Low Band + Vertical Polarisation.
Low Band + Horizontal Polarisation.
If a DVB-S card were to have dual tuners, but only a single input, it would only be able to record two channels if they were on the same combo option from the above list as they are mutually exclusive.
With DVB-T there is no such interaction with the antenna.
TV Channels are encoded in a digital bit stream (Called a multiplex in DVB-T speak) - there are multiple channels in each stream and each multiplex is on a different frequency.
If you want to record two or more channels with a single tuner, you can only do this if they are in the same stream.
There are six multiplexes in the UK, so with 6 cards it should theoretically be possible to record every channel simultaneously. Now that would be an impressive system! :-D
4 cores
The comment made by Heather that "nothing uses four cores yet" is not true. If the operating system sees four CPUs, and applications that run on the OS are multi threaded (as most are these days) then the OS will make use of all available cores to run the software and the platform.
How much an application benefits from multiple cores depends on the efficiency of the OS scheduler and the quality of the multi threading code in the application, and finally how much inter dependency there is on the computational tasks being performed between threads.
Is this really a Dual Satalite Tuner?
Is this card (as it implies) a Dual tuner on DVB-S i.e. it can record one DVB-S channel and you can watch another?
Also does it fully support HD (on both tuners!)
Thanks
RE: Dual Tuner
Its not a dual tuner, I'm not sure where you think this is implied? The image shows that there is only 1 input to the card?
If you need a dual tuner (watch one channel record another) simply buy 2 cards.
What inputs?
I don't know if its just my pc, but a cant see a picture, so could anyone tell me what inputs it has? Thanks
