You should read more, definitely. Practically all my answers does discussed here many times.HotRod19579 said:I currently have a 922 and a 622. My 922 has the OTA module allowing me to record 4 channels at a time.
How buggy is the Hopper?
Still buggy - you'll need to read the forum.
Can I depend on my recordings being recorded and available?
Yes, also use EHD to migrated them to new H2k and keep them out of heat.
My 922 is still a little buggy and I tend to lose some of my recordings. Should I wait a little longer before upgrading to the Hopper and let some of the existing issues be resolved?
Not really, you will have to participate in gamma testing and report all bugs here.
With the 922+OTA I still have some occasional timer conflicts but I am of the belief that the Hopper will solve this with the new prime time recording feature. From my reading it sounds like I will be able to record primetime for ABC, CBS, NBC and FOX plus two additional channels, is that correct?
Correct.
It is my understanding that the primetime recordings are stored in a reserved short term buffer on the disk.
Nope.
Can the recorded programs be moved to a more permanent area on the disk?
Yes, actually it will be out of expiration and available to you after regrdless of the 8 days limit by default for PTA.
How and can some programs be automatically moved without using an additional tuner or does it require a manual action to move the recordings to the permanent area?
Can't. Use your timer or move manually.
Can I get two Hoppers to replace the 922 and 622 and if so, what will the monthly cost be in comparison?
Written many times - read that initial thread "Installing ...".
What would be the monthly cost for the Hopper plus Joey? What are the one-time upgrade fees?
See main thread. You must call CSR if you'll need two H2k - it would depend of your history.
Is it true that with two Hoppers you have six tuners and the recorded programs from both Hoppers can be viewed from either of the two Hoppers?
Yes.
Using an external hard drive will I be able to transfer my recordings from the 922 to the Hopper or should I plan on losing the existing recordings?
Use EHD and be happy.
Is there any way to transfer timer events from the 922 to the Hopper or will I have to reenter all of timer events?
You could try. Remotes are different, but remote from 922 with stored info could communicate with H2k in IR mode (not sure if it will transfer into H2k).
I have a universal programmable remote, URC's MX-850. Will the same programming used for the 922 work with the Hopper or will I need to reprogram the remote?
In IR mode it should.
Does the Hopper have full support for DLNA?
Yes.
Any word on when OTA will be available?
Soon.
One of my TV's is not an HD TV.
What input it has ?
Will I be able to connect it to the Hopper?
Yes.
Joey?
Yes.
Or will I need to purchase a new TV?
Better to get new HDTV with 1080p24 support.
What types of connectors for the TV does the Hopper and Joey support?
Any.
