What a find, this application solved all my problems. I had no problems with my DVD R/RW then after a downloading couple of rippers and burners I couldn't even play a DVD on Windows although CD's were OK. Tried various codecs ie. DivX and Codec Pack other that I can't even remember but this one came up trumps, easy download and install and it's FREE excellent keep up the good work.
PS Other user comments helped a lot, thanks.

Wonderful, one of the best freeware applications I have ever downloaded. A quick download and easy to install. The quality isn't the best, but for free anything is great, I can play DVDs now and that's all I wanted. Some advice to other people with this same problem or who are downloading this is to download WinDVD 7, and then use serials from www.seri***.ws to unlock it, it's a large file at 53MB compared to this, that's what I am trying now, but for the meantime I am using this program. Thank you free-codes.com!

Very good programme and convenient!!
The main advantage is that it can play files on Window Media Player

Excellent! MPC's built-in DVD decoder was too slow for my old P3 so I decided I'd give this a go. To my suprise, Dscaler worked brilliantly with great quality! Don't pay for commercial DVD decoders without trying this out first.

Tip: Set deinterlacing mode to weave if it looks 'jumpy'. Also, use ffdshow to decode audio so that you can normalise it.

V. easy installation, free and safe.
Puts itself where it should be, windows media player recognizes it automatically.
If only all internet free stuff could be as helpful as this one!
