I bought a new Philips DVR75 three weeks ago in the US for US$290(including tax), have recorded about 20 hrs of TV shows. When recorded under the 2hr mode, the quality is near original, but when I record it under the 4hr mode, the quality drops siqnificantly(also some blocks/masks appeared).

Most operations(fast forward, play...etc) seem to take 1 or 2 seconds to respond after I press the button. Did you guys experience similar issues on your DVD recorders?

I haven't recorded from other analog sorces(VCR, Hi8) or DV yet. So I cannot comment on its performance in those areas.
