I think by "see all the log entries" you mean to see the contents of the files?
If so, the easiest way is to "ls -t | xargs less" (use ":n" to go to the next file, ":p" to go to previous file). The command "xargs" take its input from stdin (the pipe) and puts that content on the end of the command. So if its input is "a", "b", "c", then it effectively runs "less a b c".
An alternative, and perhaps more readable, way is to use backquotes (the key next to the 1 key on a normal UK keyboard). So "less `ls -t`", though you have to be a bit more careful since it would run the "less" command even if the "ls" command returned no output, and some commands would then read from stdin instead. (Young people prefer "less $(ls -t)" as equivalent to backquotes).
So, if you wanted to grep perhaps you could use "ls -t | xargs grep -e Arrow -e Strain". And if you wanted to view those files you could "ls -t | xargs grep -e Arrow -e Strain | awk -F: '{print $1}' | xargs less". You could replace "xargs less" with "xargs cat | less" if you don't want to just view all the files in one long list.
The autorecs will work properly, but I think series link is a bit complicated and, as you say, BBC weekend news probably has a different series link to BBC weekday news, even though they have the same title.
I always manually create my autorecs on the autorec tab. It's a bit more tedious than doing it from the EPG tab, but it does mean you have better control.
