[MEncoder-users] Duplicate frames when encoding from TV?

[Carl Beech]

Hi,
 I've not sent a message to this mailing list before - if I've not got the 
right address / details please let me know!
 I've been using 'mencoder' for some time, and have achieved at 25fps 
640x480 recording direct from the tv input (v4l), using lavcodec video and 
pcm audio. - All on a 1Ghz Duron processor with 256Mb memory.
 Over the last weekend I've upgraded my motherboard, processor and memory - 
I'm now running a 2.4Ghz Sempron with 512Mb (400mhz) memory. (I've kept my 
original disk drives)
 Theoretically the new board should chew through tv capture using the same 
settings - but it isn't - I get a 'duplicate frame' message about every 
second, and I get approx 24fps. - The disk drive light is hardly 'on'.
 I've re-compiled from the new 'pre7' release (admittedly the old setup used 
the 'pre6' - but I did install that from my own rpm's and it didn't seem to 
make any difference).
 Can someone tell me what I'm doing wrong? 
 Many thanks in advance....
