Sports-videography IMHO is no different to any other kind of videography. To achieve smooth motion the rule of thumb is – just like you wrote – “shutterspeed = 2 x framerate”. If you use higher shutterspeeds, especially with fast movement of the subject or the camera, the result will be strobing and what you descibed as flickering.
I did a lot of tennis-videos the last couple of years (not with my DSLR though) and almost always used a shutterspeed of 50 @ 25p (or 50i – to be more precise). The max. shutterspeed I found useable was 100. Higher than that gave me too much stuttering for my taste and needs.Concerning DOF: I’d guess it depends a lot on what you’re about to do with the footage and what you’re aiming for. Shooting sports with a DSLR is very hard, *because* of the shallow DOF and the not very … well … easy handling … If you want to achieve a “filmic” look, shallow DOF is a must, but very hard to maintain focus, especially with a 50mm on a crop-camera (on the T2i the 50mm is an 80mm on a full-frame, therefore a “telephoto” lens).
I’d try to use the highest f-stop possible, to get the narrowest DOF. Even with f8 or so you’ll get more “filmic” pictures than on a camcorder with a much smaller sensor. A wide-angle lens would be perfect.
Hope this helps a bit…

A very common method is the so called “PAL speedup”. Thats the way 24p movies are broadcasted on tv in Europe. Just tell your NLE to treat the 24p clips as 25p (“Interpret footage”). You’ll notice a speedup of about 4% and a slight pitch in audio.
A simpler way is to just put your 24p footage into a 25p sequence. Just like Steve wrote, Premiere does that more or less flawlessly. Sometimes you might notice stuttering in your clips. That’s because there’s no simple mathematical way to convert 23.976 to 25. But most of the time it’ll work quite good.——————————————

I double-backup my source material on external USB3 drives. For project-files I sometimes use Dropbox (“increment and save” to my Dropbox-folder)

If ISO doen’t come to play it seems not to be normal… Could you post a stillframe or a clip. But I’d guess there’s somethind weird going on with your camera.

Hi, Claire!
PAL and NTSC are standards for SD television, so they are of abolutely no issue, when working in HD.
In fact, even the possibility to “record” in PAL or NTSC on an HD cam like the 5DII is technically not correct.
Not sure, why the Canon engineers offered that. I guess it’s because PAL and NTSC are seen as common terms for “PAL = European video” and “NTSC = American video”. Technically there’s no difference between “PAL” and “NTSC” in HD other than the framerate.If you switch your camera to PAL, it won’t offer the possibility to use 29,97fps with 1080 or 59,94fps with 720, if you switch to NTSC 25fps (with 1080) or 50fps (with 720) are not available, while 24fps (or to be more precise: 23,976fps) are available in both modes.
So, no problem there.
The only problem that could think of, is to create DVDs from 24p material, since not every authoring software offers that feature.

Which settings do you use? I noticed vertical stripes only when using high ISO on my T2i, but I’d guess that shouldn’t be a problem with the MkIII

[Phil Balsdon] “This is probably an issue to do with electric current frequency powering the LEDs. (…) If this is the cause there’s virtually no fix in the camera.”
Yes, exactly. Even LEDs that won’t show any flicker when at full power will flicker while dimming.
