downloading problems with hd files and RTMPDUMP/ win xp

[chris chery]

downloading with rtmpdump (rtmpdump 2.3)  in the options file rarely
completes.
 the percentage is wrong  after resuming and does not convert to mp4 at the 
end if it ever gets there.
Most times it is impossible to resume when it stalls

 the downloading of human planet episode 1 systematically stalls at 41568kb, 
percentage goes back to zero and file doesnot download any more
any  suggestions?

with flv syteamer file converts to MP4 before end

 the option file as follows

lame .\lame\x86\lame.exe
mplayer .\mplayer\MPlayer-1.0rc2\mplayer.exe
atomicparsley .\atomicparsley\atomicparsley.exe
output C:\Documents and Settings\chris\Desktop\iPlayer Recordings
flvstreamer .\rtmpdump-2.3\rtmpdump.exe
ffmpeg .\ffmpeg\bin\ffmpeg.exe
vlc .\vlc\vlc.exe
mmsnothread 1
nopurge 1


 what is the solution?
 thanx
