A logo every 10 min. means they ripped the source from an HK DVD and are trying to cover up the watermark.
There are some groups that release scripts (mine does but our host's down), but I agree, it's a shame that more don't. Then again, I may be biased, esp. since R2 buyers like to donate DVDs to people who release.
As far as lousy work, TV-Nihon has some pretty horrid translations (they recruit translators starting in 2nd yr Japanese, I've got friends in 3rd and 4th getting A's admitting that they need more classes before they start), ugly karaoke, and piss poor grammar.
