Hi, I'm new to this forum, and I wish to build a new terrestrial Freeview PVR using a new PC. So I would welcome some advice on the ideal mix of components required. Currently: I have two similar proprietary PVR's each with two-tuners, so I'm able to record two Freeview TV programs (and/or radio programs) simultaneously per machine, they will also play audio files. So my new PC-PVR will need to be able to record at least 4 Freeview programs simultaneously, possibly more. So are there any established set-ups that are known to be reliable? Tuner Cards: So far, I've found these two Quad TV Tuner Cards. a: TBS 6205 DVB-T2 DVB-C Quad TV Tuner PCIe Card. @ about £169 b: HAUPPAUGE WinTV-quad HD PCIe TV Receiver (Item model number: 3875199) @ about £100 ...but I'm not sure if either have a good reputation, for performance, reliability & longevity etc,. or if one is better than the other, or if there are others worth considering. Operating System: So is Windows the best OS? If so, which version? I'm familiar with Windows 7 64bit Pro, as I'm using it on my regular PC. Or are there better OS other than Windows? PC Case: My current PVR's are in quite low cases, only about 3 inch (75mm) high. Can something this low (or similar) be achieved with a PC-PVR ? If not, what would the typical case type and size be? And it would need to be quiet! MotherBoard: From past experience of building PC's, I've learnt that you don't know what features you've not-got until you need something specific, and that's when you find out that you mobo doesn't have it! Also, some motherboards seems to have inherent problems that only seem to become obvious after you bought them. So what features should the ideal PVR-PC motherboard have? And are there any particular models that you can recommend, or advise against? I'm sure there are many other things to consider, like: How does the EPG turn a PC-PVR on&off; Remote Control Operation, etc. I guess I need to start with the TV Tuner Cards. All advice appreciated.
