Youtube seems to have what you want. I don't think there is anywhere else for these old series.
This one is '包青天' and is in MANDARIN.
This is '新包青天' and is in CANTONESE.
This is '新包青天之七侠五义' and is in MANDARIN.

Or you can try the search yourself with the above words. Enjoy!

Also, there doesn't seem to be TWO versions of 包青天 in 1995. Found out that the original version was from Taiwan and was brought by both TVB and ATV (both tv network in hong kong) and they both aired this program at the same time. Source:
