Welcome to the forums.
My suggestion would be to use something like HDVSplit to do the capturing and then import those captured files into PPro.
Striping a tape won't help. The camera records new timecode over that anyway.
Never remove a tape, or initiate playback, until you're done shooting on it.
Use End Search-button that will get you right back to the last frame recorded.
No need to stripe the tape, i do recommend new tapes to be wind and rewind once before using. Buy a seperate (re)winder for this.
...or, always look at the timecode display in the viewfinder or the LCD before you press REC. The nice display will ALWAYS indicate when you've reset the timecode. If the display is 00:00:00.00 or similar and you are NOT the very beginning of the tape, pressing record will start a new time code sequence everytime.
If you have END SEARCH, use it. this will usually work as long as you haven't removed the tape. Either way, rewinding the tape until a non-zero timecode appears and then pressing REC works. The camera will increment the timecode from that value..
I'm not at my editting station, but I seem to remember that PPPro has a capture setting that will cause it to ignore timecode breaks--you then edit out the rough section at each break when editing. Unless you're going to do something clever like recapturing HDV after capturing SD, you're not going to use the timecode anyway.
Then in the future, always look at the timecode display before you press REC. There is really no reason to stripe if you always remember this.
