no xv
such slow systems (like p1 or old celerons) usually has no xv-capable cards
but dga or vidix or xmga (1 buffers) could work there fine
it was tested with dga, and it worked well on p1 - search archive, it was
done a year ago (!) by Acki (similar DR hacks like yours - but never comited)
again: on p1 mmx with no drops, not on celeron 266 with drops as yours

LGPLed. not GPLed.

there are no shared objects nor LGPL

ans we'll remove this stupid license as soon as we get rid of things keepeng
us away from binary packages. but you'd better RTFMing

dunno. many, including all code by me.
i'll switch to gpl my code as soon as we get rid of other problems

yes

yes

even dd if=/dev/urandom of=mplayer  works sometimes... rare but possible!
