These were recorded with my personal PAL vcr. It is kind of an old piece of junk (Panasonic NV-SD25, with mono only audio). My NTSC captures are nicer.
The captures that we had professionally done were not all that great. They introduced a number of frame blending problems, as well as quite a bit of pixelation.
I have NTSC tapes for episodes 1-8 and 10-13. Here are raw captures of the Japanese NTSC tapes untouched with any editing other than an IVTC to do some decombing.
Where your captures could come in really handy is if you are able to get a good capture of The Great Heep. As there is no NTSC tapes of that (that I am aware of).
