    Got the Panny E85 and I read in the manual that if you choose PCM in XP mode, picture quality is reduced. Does the same apply when recording to HDD?

    PCM uses up a lot of the bandwidth so therefore reduces that which can be used by the picture.

    That;s interesting. So even though it takes up more space on the HDD, it's inferior PQ?

    Yes - because the HDD content remains at all times DVD-Video compliant. If the PQ was maintained and LPCM used then the collective bitrate would exceed the maximum allowed by the DVD-Video specification - which means if you wanted to dub to DVD-R you couldn't (unless you re-encoded).

    For music videos is the sound quality of LPCM better than D/M2 (384 kbps) - I have a tosh 32.

    Would the difference be noticeable if recording from VHS?

    Yes, LPCM, being an umcompressed format, would be "better" - but unless the audio of the input, your sound system, and your ears are all very good you won't notice. I doubt you would notice from your VHS recording.
