FAT32 on a DVR? What a brilliant idea, especially given that the maxium file size 4 GB - so if you're recording a longer movie, forget about actually watching it! If you're any serious about getting a DVR, a MythTV box with a reasonably sized HD (formatted in XFS/JFS) with a couple of DVB tuners will yield much better results, and actually won't cost that much - my >5 years old Athlon XP 2600+ with 1 GB of RAM happily records four DVB streams while watching one (it could do eight from two multiplexes, but there's never that much to watch at any given time), and with proper deinterlacing it looks great even on a 1080p display.
