Doesn't sound good. If not under warranty, you could get a look under the hood, and visually inspect the lense (suspension of lens is VERY delicate, use extreme caution cleaning with a Q-tip & alcohol)Don't have experience with the DV-29, but I cleaned the lense of my dvd-a player, that had been rejecting about 20% of discs (dvd/dvd-a)& improved to rejecting 5% initially & plays all with multiple attempts. Don't know what mechanism arcam uses in this player, but replacing the laser isn't major rocket science if your are at all "techie" inclined. Look here:http://www.diyparadise.com/cd46/cd46repair.html Laser assemblies usual run $20-$100 from mcm ,etc.(could be something else amiss, but weak laser diagnosis fits symptoms) How does the player sound?,quality wise, been interested in that model as a sonic upgrade from my 1st generation,pacific rim model...
