check programmed recordings you will have a clash possibly in time and date on another channel. If the dvd records two channels at once normally check if it has two channels already set up at the same time to record i the scheduled recordings.
you may have two different channel positions that are the same tv station and have set up two different channels to record the same show. and then you may be trying to record another different channel at the same time. check and delete extra channel schedule.

Another way to have this is as an example say programmed record at channel nine f0r show 1 at 7:30 to 8.35 day xyz and then you set up show 2 to record at channel nine say from 8:30 to 9.35.day xyz this will use two time frames during the overlap from 8:30 to 8:35 on day xyz and if you decide to record a third show you can't between the overlap time frame

every 10.000 klms or six months is the recommended schedule for oil change . You can change the oil earlier for adverse conditions

Adjust as desired

This worked for me.....(from the Top Up TV website)
Purge VOD.
Press the menu button
Scroll down to Option 4 and press OK
Scroll down to Option 6 and press OK
In the help menu press 1397 on the remote control quickly and in sequence
Scroll down to the 'Purge VOD Schedule' option (next page) and press OK
Remember the DTR must be either on or left in standby at all times to receive the EPG and programme downloads. • The guide will update at the next scheduled slot (between 11am and 12pm daily).

Updates are also quicker if you change from 14 day EPG to the 8 day version...

I will assume you did a OS upgrade and didn't check compatibility with Win 8. Did you have Win Vista? Or Win 7 before? That said, drivers for the Video will be on the DELL website. SOMETIMES you can use Win 7 drivers. You may have to change compatibility of the drivers. You didn't say is you had Win 8 32 or 64bit?

Be sure you have the right time zone selected in settings. It sounds like that may be the problem.

The PS3 network is currently undergoing scheduled maintenance. The servers will be down for approximately 11 hours commencing at 8:00 A.M.Pacific time, and are scheduled to be back up at 7:00 P.M. Pacific time. You can check the following link to get updates on the time that they are expected to be back up:
