Phil,
When you get the "All", "Entertainment", "Lifestyle" channel selection options on screen, hit the upward arrow and it takes you to the menu level above. On there, scroll across until you hit an icon that looks like a magnifying glass. That's the search function.
Enter whatever word you're looking for (in my example "photo"). To enter a word, it's the same idea as a non-predictive text mobile phone. On the handset, the numbers have "abc", "def", "ghi" etc. on them. Hit the appropriate buttons repeatedly until your word appears in the box on the screen and hit enter.
Anything that starts "Photo" appears as a list and it tells you what channel, when, etc so you can record / record series and all that kind of thing.....
Hope that makes sense.
