Yes, should be fine.
What kind of cable lengths are you looking for?
E.g. 1.5m length cables for both are just over £6 at 7dayshop (compared to £10 in your link), with the free delivery option:
DVI-HDMI cable (1.5m) click here = £3.29
3.5mm Jack to 2x Phono (RCA) (1.5m ) click here = 2.99
I have used them a few times with no problems. Items are sent from Guernsey. G
