[mythtvnz] IDE-SATA adaptor?

First I want to say thanks for all the replies, the fact I have
replied to Stephen doesn't mean the other posts were unworthy of
acknowledgement.

You still run OS/2? Wow, I remember getting a free copy of warp on
floppies on a magazine years ago. I liked it, couldn't understand a
lot of it. People claim that OS/2 boxes have been accidentally sealed
up in cupboards and left running for years without intervention. I
also seem to recall that there was some open source software like
sendmail available for it?

Actually I realised that the PCI slots are taken up by DVB-S cards
that I am not currently using as I have 2 HDHRs. I could put a PCI
Sata cards in there. Would still like to make good use of the IDE port
though.

I use exclusively UUIDs in fstab so that should not be a problem.
Saves a lot of headaches.

Actually when reading the list after posting, and looking at the
offerings I thought about upgrading the motherboard and processor. I
bought this backend box at a tight financial moment (think I had just
bought the house, and the old one blew up and needed immediate
replacement. I bought a cheap "upgrade" box, you know just the box
with a motherboard, ram  - no hard drive. Wacked the old hard drives
in and DVB-S cards in and away I went. Hence it is a Sempron 1GHz with
1G RAM. IDEx1, sata x2. Single core, not even hyperthreaded. I don't
comm flag, It even takes a while to index my music files under
squeezeboxserver. Lots of room for hard drives in the case though.)

Yeah see above. What did you get? And from where? $550 is an OK
budget. The whole family now is thoroughly familiar with both myth and
xbmc, so it's a investment for the whole family (isn't it???).
