-cant play AC-3 through the rca plugs or the HDMI directly to a TV
-once in a while it chokes on a high bitrate feed playing it (My Network HD comes to mind)
-cant record high bitrate feeds
-if you press the buttons on the remote too quick it freezes up
-doesnt like low symbol rates (under 2500)
-if you select anything other than 480i through the av cables you get nothing on the screen
-wont keep time at all. if you select manual time and power off, when you power back on it shows 00:00
-Renaming channels is useless on some sats. The "blind scan boogie" sats (72,74,79,91,105 as example) dont bother renaming channels because if it rescans the TP it puts the old name back...I renamed "service 1" on 74W as ONN. Blind scanned and now it shows "Service 1" again.
-no way to select a specific satellite in the list. You have to scroll through them
-Still no way to setup a diseqc switch in motor antenna menu...I have a 22k switch in the line. Can only select the KU LNB....when you pick motor there is no option for a diseqc/22k switch
-locks up on a dead channel (feed) if you power it on from that channel
-Can't Save Channel list
-Firmware update resets everything
those are off the top of my head...there may be more
