I have recently upgraded to a 322 from a 3900. Man its quite an upgrade especially in the EPG, no more waiting what seemed like 10 minutes for the info to appear.
I have noticed a couple of issues that I have emailed Dish, and now we are going through the dog and pony show of checking everything in my system info.
The issues I have seen:
1. Timers. I set timers to recored to DVD for timeshifting every night. I have on three different timers noticed that the box turns on at the right time, but I get a black screen (on both S video and also ch 4 from the 75 ohm connection).
Maybe a coicidence, but all three timers with black screen were on Sundays.
The first time this happened, my timer from 8 to 9 PM was black (I missed the ending episode of the Amazing race). The timer from 9 to 10 PM recordered normally (full video and sound, no problems).
The second time this happened I had just setup the timer and turned the box off but the TV was still on. The box started and the screen was black. I channeled up on the remote, the next channel up displayed so I channeled down and my TV was displaying what the timer should have displayed.
The third time it happened was the same as the second. I no longer trust the box so I watch to make sure the box turns on right at the first timer.
2. Guide. Sometimes I cannot go to the right to see later times. I press the right arrow and nothing happens. If I page down in the guide, I can then arrow to the right to see later times. I can then page up to see the later times I couldn't see on the channels until I paged down, arrowed right, then paged up. This is minor as it is easily worked around.
I tried searching before posting and went back as far as January which was a time of older firmware as I believe these issues to be firmware related.
I am current with L421 firmware.
Has anyone seen this? The timer issue is something I have to "babysit". So far I have not seen this happen on any other day but Sunday, and only on my first timer of the day (one of the timers was sunday morning).
As for your timers resulting in black screen. I, too, had the same annoying problem for quite a while, until I played a hunch: I set up the 322 with a VCR remote code following the VCR Set-up via the Menus, and ever since I have NEVER had a black screen; all timers have fired 100%.
In other words: if you did not set-up the VCR timer function, and did not provide a VCR code during set-up, the timers won't function correctly.
Solution: From the table of VCR codes provided, select a manufactuer code that won't interfere with any of your equipment. I selected an RCA code, as I won't have any RCA products. Enter the code following instructions. Your timers should work properly.
One more thing just to ensure no black screen. Although this seems not to be a problem after entering VCR code, in the past the 322 TV1 would have a black screen if the timer was set to fire on the very same channel that the box was tuned to when it was last shut off.
I found the TV2 timers to always fire, no matter what.
As for your guide problems: I have experienced this only about 4 times approaching 2 years of use. However, a re-boot fixed the problem. I can't say that this guide trouble amounts to a problem for me.
