[mythtv-users] Is transcoding livetv really necessary?

[Lord Darkhelmet]

I would like to know what you have your capture and transcoding settings 
at if you don't mind sharing.   Currently I capture 640x480 with a 
bitrate of 4500.  This yields about 2.2gb per hour.  If I then transcode 
to 640x480 with a 2200 bitrate, it cuts an hour down to 750mb but really 
hurts the picture quality.

Thanks.
Dean.
