color depth is a good idea, doubt I would have thought to suggest that one the higher the bitrate the less compression the encoder perform, but the more storage the recording takes up, so better picture quality
however, keep in mind the higher bitrates will eventually be to much for the speed at which your system can record it to the hard drive(s), then you get dropped frames -- much worse than blocky (yet) uninterrupted video lowering your resolution from say 720x480 to 480x480 means less detail (more blockiness) but that also means less data to be stored by the hard drive (less chance of dropped frames) ----- Original Message ----- From: Kevin Kuphal <[EMAIL PROTECTED]> Date: Tuesday, February 8, 2005 3:57 pm Subject: Re: [mythtv-users] picture blockiness > Nick Collier wrote: > > >All, > > > >When I'm watching live tv, I've noticed I get some blurry blockiness > >in places.
