Query: DVR 1600 MU1 - Buy it on your own risk

I have given it two stars only because of the Cyberhome customer service. Actually, there is no customer service. Here is their message on 888 customer service number:"Thank you for calling the Cyberhome Entertainment service center. If you have any questions regarding the operation of your product, we have an extensinve knowlegde base to support you at www dot cyberhome dot com slash service. Our phone and e-mail support is currently not available."No comments!I did not find the answer to my question at this WEB site.There is no way you can post your questions on this WEB site.There is no way you can get an RMA at this WEB site.Otherwise almost all functions worked properly for me, except for playing back the recorded DVDs on the computer. There was no sound. I can perfectly watch any other DVDs on the same PC, but not the ones recorded with Cyberhome DVR 1600 MU1. I am going to return this DVR back to the store.Good luck!
