It totally depends on the bitrate. If you are familiar with the technology, you know that MPEG-1 is the almost 100% identical to MPEG-2 when it comes to coding progressive contents (films), and MPEG-2 is what is used in DVD.

So what you are saying is: DVD is basically VHS quality. But you know it is not true. The reason is simple: when you throw more bits, you can get quality as good as you want. MPEG (1 or 2) at 4 or 5 Mbps has DVD quality.

Yes this is characteristics of MPEG-1 encoding *at low bitrate*, that's because of the lack of quater-pel motion compensation and bloc filter, we all know that. But still, your 800 Kbps appears to be globally inferior quality compared to the v3 1.7Mbps MPEG-1. Again, that's my opinion. And I agree that your 1.1Mbps is as good (or slightly better) that the v3.
