<DIV><FONT face=Arial size=2>I'm no expert on the BBC ouput hardware but would
it be possible to hack the hardware to output the same line twice at double
speed or would this be asking too much of the hardware? I've often wondered when
I've been rearranging all the monitors on my desk!</FONT></DIV>

</BLOCKQUOTE></DIV><BR></SPAN>I'm not an expert on this, but going by the
figures you've just given, I'm thinking that this isn't going to work. This is
based on the 30kHz figure you've given, the Beeb's PAL output having a line
rate of 15kHz. Unless of course you use some kind of scan-doubling device -
I'll leave discussion of those to others :-) <BR><BR>-- <BR><SPAN
