I have made some progress on fixing this issue, but its not working yet. I’m not a developer, so hopefully someone more knowledgeable can help get it working again. YouTube has published a helpful ‘Migration Guide’ here:
http://code.google.com/apis/youtube/migration.html
Based on this, I changed genki_youtube_comments.php line 147 from
$source = file_get_contents(“http://www.youtube.com/api2_rest?method=youtube.videos.get_details&dev_id=$youtube_dev_id&video_id=$videopost->meta_value”);
to
$source = file_get_contents(“http://gdata.youtube.com/feeds/videos/$videopost->meta_value/comments”);
Now the plugin successfully prints the WP permalink, but then throws the error “Error retrieving data from YouTube”. There must be some other syntax change required, but I’m not a developer so I’m shooting in the dark here. Can anyone else help?
