Episode 21 - You Have Just Been Murdered

A note on the timecodes
Where I have listed two sets of timecodes, the first is from the 2009-11 Optimum Releasing/Studio Canal DVD sets, any other timecodes are from the A&E and Contender DVD sets from a decade beforehand.
The new releases have been remastered and their frame rate has been changed, resulting in a shorter running time. However, the picture quality has increased markedly. I assume this is because they used a simple 2:2 pulldown (24 @ 25) when converting from the original film masters (film runs at 24 frames per second, while PAL runs at 25fps, the new DVDs are in PAL format).
This pulldown was also the cause of audio errors on many episodes, especially for Series 5, as the audio sped up to match the new rate (4% faster), rather than being properly pitch-shifted. Checking the dialogue sheets, which list the feet and frames of the reels, it looks like the speed change is around 5.04%, so there may be some cuts as well - probably from around the commercial breaks and ends of reels, as they amount to about 25 seconds. All my assumptions are based on the episodes having been filmed on standard 35mm film, which has 16 frames per foot and runs at 24 frames per second, so a minute of footage uses 90 feet of film (1,440 frames).
These audio errors have been corrected in the currently available DVDs, but the 2:2 pulldown remains. There is also the addition of a Studio Canal lead-in, converted to black and white to match the episode for Series Four, but colour for Series Five, adding an extra 18 or 19 seconds to the runnning time and making it harder to match timecodes with previous releases. It's annoying that it has been slapped on every single episode, Series 1-3 didn't suffer this indignity.
The previous Contender and A&E DVD releases didn't seem to suffer from these problems, so I assume they either used soft telecine and preserved the original 24fps rate of the film (my preferred option in DVDs) or they used 24 @ 25 pulldown (2:2:2:2:2:2:2:2:2:2:2:3 Euro pull-down). Let's hope the much-rumoured bluray release will revert to native 24fps with soft telecine so we won't have these problems again.
