Record as i watch from megavideo

[venga]

I have been trying to watch and save(record) the megavideo videos from quite some time
Techniques i have used so far...
IDM ...doesnt give resume facility
replay catcher, jdownloader, Replay Video Capture...too slow
The max speeds it downloads is 10-20 kbps where as i can download in 50-60kbps with normal downloads using idm

When i play the video ,the video play smooth with occasional buffering
so what i decided is ...
when i watch the video ..it also need to be recorded or save somewhere with out taking double bandwidth...
(i think in replay catcher case if i keep watching same video in browser and start download ,it will be downloading in 2 places)

I tried vlc media player but it is not able to play MEGAVIDEO flv link(i got using idm or replay media catcher)

so what can i do ...

i want to watch and record video of megavideo

last option is screen capture
problem with that >buffering and low quality
i noticed real player record doesnt work with online stream

any software i can use
thank
