Wow, didn't realise how expensive HDMI to S-Video converters are. :eek:
If the OP has a home cinema system they could connect it through that.
If not it might be worth considering upgrading to one as much more fully featured A/V receivers can be bought for in or around the same money as those adaptors.
Add a cheap set of speakers and you've got a full surround sound system.
Either that or a nice upgrade to a new flat screen TV with HDMI.
