#1 Please don't top quote.

#2 Please don't drop cc's to a mailing list if that is where the mail

Analog video support added for the HVR1800 does _NOT_ break Digital 
video support.  You can use digital and analog simultaneously.

Be advised, however, that the cx23885 driver currently does not support 
DMA audio for analog preview, but audio does work for mpeg encoder mode.

However, don't use the master branch today -- the build system is broken 
right now.  Instead, use:


Please send future correspondence to the mailing list.  you may feel 
free to cc me, but remember the mailing list is most important.
