I'm in the process of planning my next PC and am considering trying to add a digital terrestial PVR function to it. I already subscribe to DigiGuide and am looking at Showshifter for the media centre aspects. However what is a good PC digital tuner? I see from many of the threads that alot of people recommend the Nebula PC cards? Are there any models to avoid/any that are very good? Am I correct in assuming such a card records the bitstream as broadcast (and thus is lossless)? If so how easy is it to import into an editting programme, do frame accurate edits and author to DVD-R? Do you use re-encoding software to 'fit the recording to disk' - if so what programme(s)? What about PC hardware? Do you find that using your PC as a PVR is wearing on your HDD? Have you found it better to go for fast HDD such as SCSI or RAID or will cheaper, more conventional solutions be as reliable? Do you have a seperate HDD (from the one with Windows installed) for your PVR recordings? I'd be greatful for anyhelp on this subject!
