You might need a faster card

60D card interface limit is about 21 MByte/s and balancing on the edge will make mishaps happen.

You might try to lower the resolution just a little; the added color depth in RAW should more than compensate. Go ahead and try different res'ses and compensate in post production. The 60D is a fine instrument; with some experience you'll find the perfect balance between res and color rendition.

thank you all for your replays ...... 

so the test results 1600x680 3:35:1  (1)frame dropped
                              1600x680  16:9    (1)frame dropped
                              960x408     3:35:1   ok!!!!!!  (but its 960x408)
                              1280x544   3:35:!     ok!!!!   (but still its not at least 1600x680..)

in all my test and before 1 frame evry time...(ok ou will say to may its ok if its 1 frame .. but..its not beautiful for the film...)

but that comfuses me is that when i write in raw and not in mlv (the older recorder of raw) i have not missing , skipping , dropped frames.....
so this is a problem of the firmware ? the camera?
i konw 60d is a fine camera i love it i wish to have a 5dii but no money no honey...
so my new question is why in mlv = dropped frames and in older raw = all fine ???? (i have  enembled 1 feature at the time .. no sound rec mlv no mlv viewer ) thank you all
and raw vs mlv =??? what is the diference (its only for the workflow or do the mlv have other benefits (exept the audio...coz external recorder for the audio))

Use a different version of raw2cdng or try a different converter.
