I have met "Removed by creator", "Removed for copyright infringement" and "Not available in your location" but not "Video not found or Access Denied".
I certainly have made every attempt to ensure that the video is as public as possible without posting it anywhere except RZ and YT. There are older and newer versions of it though.
I originally worked on it as a 1080p clip, and didn't realize until after I uploaded to YT that the overlays and callouts (stuff drawn over the screencast to highlight areas of interest) where not rescaled when I ran the footage to press in only 720p.
I switched to a 720p production; slightly last minuet, because I decided to use zooming and panning to the locations of activity, so that non-HD (360p / 480p) resolutions weren't completely useless.
I'm pretty sure I updated the link on RZ, but kept the original YT video up with a large YT linking callout overlaying it which points to the newer (and clearer) version. (It's possible you are getting the older version, and that overlay link is causing problems. Or that the captions [subtitles] are scripted in a way your proxy doesn't understand.)
I can't say the 320p version is exactly easy to follow, but I do use quite large and clear text in Olly (compared to the default) and even scaled down from 720p (which I matched as the maximum zoom) it's just about readable.
I can post an MKV file which can be downloaded and have all the subtitles in all languages embedded... the only problem with that is that I would have to re-upload each time I add a subtitle track, where YT can be watcher without downloading, at a bandwidth which suites the viewer and just upload new subtitles as people submit them.
Or I could upload a 720p MP4 (OGM or even AVI) file and separate .SRT / .SUB files for each language... but it sometimes happens that different players loose synchronization when reading subtitles from external files... or they don't pick them up at all unless you rename the subtitle file just the way the player wants. And how the player wants seems to be different for MPlayer, VLC and MediaPlayer Classic. Windows Media Player and QuickTime / iTunes don't seem to pick external subtitle files at all.
So you can see why I prefer to use MKV / OGM / MP4 with embedded subtitles where possible.
матрёшка (matroska / MKV) is my favorite, because it's theoretically possible to add chapters and DVD like menus and interaction, as well as variable frame rate footage. So you don't need to encode multiple identical frames at still sections. (though all of that is still quite difficult and technical to achieve) Animé people love it too, because the frame rate in cartoons is usually increased during high action scenes and reduced in largely still scenes.
Besides which, I like the dolls. :lol: I picked up a couple on a bus tour of Russia and Eastern Europe during the last days of перестройка. (Perestroika / "The Restructuring", I'm not sure what it may have been called in the PRC, or if national press where even allowed to comment on it at all)
If any of these sound more, or less useful to you... please say. I would like to accommodate as many people as possible. (so long as we are talking PT... Most people who comment seem to want to know how to deal with XTrap in other games. :grr:
