A new part number for the TiVo Premier DVR has turned up on Amazon and other websites. The new part number is TCD746500 it seems the only difference between this and the original is the price and the amount of storage inside. The new TiVo Premier has 500 GB of storage.
The new 500 GB unit sells for $149 compared to the $80 that the original TiVo premiere sold at. However, the original TiVo Premier had a 320 GB hard drive. The extra storage space is enough for about an additional 30 hours of HD programming.
I think that extra cash is certainly worth the upgrade for more storage. No other differences are noted and the new model hasn’t been officially announced. We expect to hear more soon.
