Thats not good
I personally think u have been unlucky..but at the end of the day its up to you as to whether you switch brands.. what would you consider as a alternative?
I also have a DV88+.. Heres my little history (I also think I have been very unlucky..)
Bought Dv88 Feb 2001
Stolen July 2001
Insurance Replaced Aug 2001
Drive Mech Broke down Aug 2002
Replaced Drive and upgraded player to DV88+
Dec 2002 Replacement drive on the blink - back to Arcam..
New Mech fitted and I pick the player up from my dealers tomorrow.
I have also thought is this worth the hassle. My old Pioneer DV606 player has been working for years (now with my brother) and I also think why I am having these problems after paying out so much money..
At the end of the day the sound and picture quality is astounding on the Arcam, and they are a much smaller firm in comparison to Sony/Pioneer, they offer great customer service which helps smooth out these problems.
Look at the problems and glitches associated with a couple of the Denon Higher end players (2800/3800).
Basically if you spend £100 on a player and it breaks most ppl will not mention it and buy the next one, ppl like us who decided to spend considerably more , are therefore far more vocal when they go wrong.. and now I am rambling...
I would talk to your dealer (or Arcam) and see if you can get a player which has been checked before you pick it up.. maybe it was a bad batch...
Hope u get it sorted..
Cheers
Matt
P.S I do admit I am very Arcam biased and really like the player (now that most of the software oddities have been sorted - still hate the remote though

). I cannot see myself changing player now until we move from DVD to the next audio/video format (or it self destructs !) and I am impatiently waiting for ther DVD-A upgrade. I have always been very pleased with the efforts of the customer support ppl who work at Arcam.. and now back to the movies....
