Yeah, Just Link and Burn Proof have the same effect at current writer speeds. If writing speeds get up to 24x or so, Just Link will have the edge because the size of the gaps it creates is shorter, so at ~24x the Burn Proof gap length becomes long enough to mess with the reed-solomon error correction that the cd's use. Just Link is probably good for up to around 50x write speeds.
But, you can count on Burn Proof being modified for shorter gap lengths once 24x writers come out.
I'm an owner of the above mentioned DVD/CDR/CDRW driver and think it is great. Only problem was the DirectCD in EasyCD 4.5 didn't work with it. Don't know about EasyCD 5.0...
