Heating issue. If you remove the cover and touch the processor chip - you will not be able to keep your finger there for more than a second (that is if your really want to use this crude method to test the temp).

I have taken measurement and its around 50C. Thats a lot for no heatsink or cooling fan.

If you have the unit in a cabinet with no air flow - you will not be able to use this unit for more than 3 months and up to a year. Best to have it on top of a cabinet or in one with an open front and back to allow some airflow - or just anywhere where its in the open.

Samsung has another unit - the AR650, which I believe is discontinued - which for some strange reason has realized this concern. My guess its a whole different team of designers (or at least some folks with some brains) and added a cooling fan into the unit. Its the same exact case and motherboard as the 135, and 155. There are absolutely no issues with it rejecting disc's - even after a year of use for some users.

In Summary:

Solution 1 - Place it in the open
Solution 2 - Remove case and drill holes to the topside
Solution 3 - Remove case and add a fan
Solution 4 - Remove case and add a heatsink over proc (will still need to drill holes over heatsink..
Solution 5 - We can all complain to Samsung and have them recall the units

I my DVD-HR735 wont recognise any discs at times, and is getting worse. I've now discovered (out of frustration) that if I tip the front up to between 30-45 degrees, it will play all the discs it says were unreadable. I've started jamming three dvd boxes under the front of the machine when i want to play dvds.

You have a dirty laser lens! There are two different ways to solve this problem on this unit...( and yes, I do own this unit and have cleaned it both ways)! 

First and most simple method.......Go to WalMart. Spend  $15.00. Buy a DVD laser lens cleaner. Follow the instuctions. Use after every 10 hours of play.

Second and more complex. On excessively dirty lenses that have not been cleaned with the above mentioned product....get a Philips screwdriver.
Remove three screws in the rear of the unit, and two more screws ....one on each side of the case that hold the top portion (black in color) of the case together. This top portion will simply slide off by pulling it backward from the from the faceplate (which does not need to be removed).
If unplugged, plug the dvd player in and eject the tray. Unplug the player leaving the tray out. Locate the laser lens.... (a clear piece of plastic that is round and about 3/16" in diameter). The lens will be facing up towards the top of the player.
Get a Q Tip and some Windex window cleaner and wet one end of a Q Tip and clean that lens throughly and dry it with the other end.
Plug the player back in and close the tray.
Unplug the player and reassemble the unit.
The next time you plug your Samsung DVD VR330 in and to play your DVD....IT WILL PLAY.
EVERYBODY HAVE A NICE DAY!!
