Sorry, I meant this:

Only relatively infrequently do I use get_iplayer in "real time". I receive a daily email of my favourite "--since 24" search preset (check out get_iplayer's "--email" option - I'm really pleased with it), I just "--pvr-queue" programmes that I'm interested in (or add series using --pvr-add) and then run `get_iplayer --pvr` in a nightly cron job.

Each morning when the --pvr run is completed the full output from get_iplayer - about 3 or 4 meg of text like the above - is emailed to me. I think of that as the "log".

How long have you been using get_iplayer? Have you never noticed this visual corruption before? Is it only me that has? I perceive video artefacts as quite a common problem.
