My experience with Toshiba DVD players has been good in terms of the quality output but I have found them too sensitive to minor defects on the DVD (smudges, etc.). The result has been freeze ups, etc. The same disks that caused problems for my Toshibas (I have two) play with no problem.
Interestingly, the dealer where I bought my projector suggested the Marantz DV4500. He claims it plays just about everything with little in the way of freeze ups, rejects, etc.
