+.meta files have currently up to 7 lines:
<service reference>
<name>
<description>
<recording time>
+[<tags>]
+[<length>]
+[<filesize>]
+The service reference contains the Service-ID of the recorded service. With
+that ID, you can find the PMT and the elementary streams.
+
+As a backup method, just find the first available PMT and use that.
+
+Strings are always UTF-8 encoded.
+
+tags is a space-delimited list of tags assigned to this movie.
+
+length is the length of the recording, in PTS-units (1/90000s). filesize was
+the filesize at the time the length was calculated, so you can validate if
+this is still up-to-date or must be recalculated.
== .ap FILES ==
If the there is no final 'out' point, the end-of-file is an implicit
'out'-point.
+Note that the PTS values are zero-based and continouus. If you want absolute
+PTS values, you can either:
+ - use the .ap file, find discontinuities, and interpolate between the APs
+ - or just use the first PTS value as an offset, and work around PTS
+ wraparounds. (simple method)
