Samsung SH875M Dvd Hdd Recorder

just a quickie, i''ve recently bought one of these, it seems fin on the whole but.... switching the unit on takes a while, the epg ( electronic programme guide) is also very slow, watching paint dry would be a better option and finally, you can play AVI files through the USB port but if you load them onto the hard drive you can''t see them to play them, although the hdd has reduced its free memory by the size of the file. Ive sent an email to Samsung about this but have not had a reply yet.
