Hi there,

Are you planning to record Sky using the output of your set-top-box  

In this case the Sky box will be converting the digital mpeg stream  
to analogue for you, and the PVR-350 will be converting it back into  
digital mpeg after you've piped it through a (lowish-quality?) tv  
cable. I'm not sure the full implications of this, but it seems  
inefficient to me, and I don't think you'll ever quite achieve the  
same quality as was beamed from the satellite.The quality difference  
may not be visible but if you use a DVB-S card then it can (as I  
understand it) be connected directly to the satellite dish and dump  
the mpeg directly from the dish to hard-disk.

As I understand it you need to place your Sky card back in the STB  
periodically to keep it working (I think it gets updates that way?)  
but I'm pretty sure it's possible to receive the encrypted Sky  
broadcasts direct to MythTV if you have the right hardware (a DVB-S  
PCI card with Common Interface slot & 3rd-party CAM) and that I've  
seen postings to the list within the last few weeks that mention  
doing this. It is not terribly well documented, but some Googling may  
be worthwhile.

I don't know anything about ZoneMinder, so it might be that you need  
the PVR-350 for that, but I hope you find these comments worthwhile.
