I also have no problems recording from the HR20 to a philips recorder, but I record to the HDD first, have not yet tried directly to the dvd yet.
I cannot seem to get my HR20 remote programmed though to work with my Philips recorder - DVDR3575. If using the HR20, What code has worked for your HR20 remotes and your philips recorder? I was able to program the philips to work fine on my Onkyo remote, but to keep things simple for the wife who likes the HR20 remote, I really really need to get that remote coded to work the basic functions of the philips. tried some searches here and on dbs forum, but didn't seem to find it. Also tried a code search with no success.
