...don't know... even if I'm really happy with what I have achieved until now, in particular lately using the HLD-X9 as source for my laserdisc captures, the result is exceptional thinking that the source is a "mere" laserdisc, but subpar in comparison to HD sources...
The idea of using the WOWOW source and another HDTV (or BD) to overlay the japanese subtitles is intriguing... about loss of quality, there will be some, but probably still lower than the BD mess, don't you think?
And, color wise, are the HDTV better than the BD?
