How to make translation of a certain node.

I would second this issue. I have the same problem in that the display block links to the raw node address without setting the language context - so it loads the node in the default language context, whether or not it belongs to that language or not.

The issue is wider than this in that the DD Block does not support URLs set with the Path module, as nodes are loaded as domain.com/node/123 rather than domain.com/user-friendly-url. This is obviously frustrating as Views normally do render the user-friendly URL (with the appropriate language context) in links to nodes. Given the DD Block is based on a View, why does the Block not link to nodes in the same way?

#1
Have a look at this issue for using Multilingual nodes with views
#2
you can add a path field (aliased path to node) to the view and map this field to the readmore button.
please post different issues in a different issues posts to keep the issues useful for other users.
If this reply does not fix it for you please post another issue.

Hope this helps you both further, please let me know.

Thanks:

For #1, did you mean to provide a link to the issue mentioned?

#2 I will try mapping the node link as suggested

For #1, yes the added link to the issue should be: http://drupal.org/node/361676
