I want to get rid of my land line for magicjack, but my old DVR that uses a modem does not work with magicjack (maybe since the transfer is too fast?).
Is magicjack an ATA? Their customer service would not give me an answer to this. Could I connect a magicjack to a ATA to a DVR so my DVR could update?

You need to drop the connection speed lower. If you can, limit the speed to 2400bps, which is the fastest speed that still uses pure audio tones to communicate.

9600 is the minimum the replay will take.

Then, you will need to keep your ReplayTV plugged into your POTS phone. VoIP and v.42bis just don't get along, because the G.711's digitization process is naturally lossy, which v.42bis cannot recover from but your human ear cannot detect.

You will be able to craft a workable negotiation between your modem and the MJ by using an ATA like the Linksys PAP2, which has the flexibility with its internal programming to overcome the limitations your are experiencing.
Plenty of info at dslreports voip forum for configuring a PAP2 to work with a modem.
