New description:

 At some point in the last 2-3 weeks the calculation of current position in
 H.264 recordings from BBC One HD, BBC HD and possibly others in UK has
 significantly wrong.

 For BBC HD it seems that every 8th frame is not counted toward the
 framesPlayed total (we ignore frames with 'no video', possibly B frames)
 and this can ultimately result in the position being behind actual by
 several minutes. This leads to bookmarks being set in the wrong place.

 A sample of BBC HD is in the samples store.

 EDIT: C4 HD issue previously described isn't reproducible so I've removed
 the detail of that to avoid confusion.
