This is, I believe a nearly complete Hill Street Blues. I have watched them all but haven't had time to check ALL episodes against an official list.
Season 1 - 17 Eps. (Includes Pilot)
Season 2 - 18 Eps.
Seasons 3 thru 7 22 Eps.
There a few very minor audio sync issues with only a handful of episodes, maybe 4 or 5 but they are easily overlooked and only last from 30 seconds to a minute. I reprocessed them all and brought most back into sync. As I say, if it does go out of sync it will only last a few seconds and this is only in a few episodes. 99% of them and in good shape.
The vid quality in about a 7 or 8 (consider the age) and the audio is perfect.
