Have technical questions about your HD home theater gear? Each Friday, our HD Advisor will answer your questions. To submit a question for consideration, send an email to [email protected] and we'll see if we can help you out. If you've already sent a question and don't see it answered yet, please be patient as we work our way through them.

We only request that you please don't ask, "When will Movie XYZ be released on Blu-ray?" Those decisions are totally up to the movie studios' discretion, and we have no more insight into the process of what gets chosen than you do.

When sending questions to the HD Advisor box, please attempt to word your questions as clearly and concisely as possible. If I'm not sure exactly what you're asking, I may not be able to provide an answer. Keep in mind that, if I choose to use your question in this column, it will be posted for the benefit of our other readers. If you can ask the question in a few sentences rather than a few paragraphs, that will make the selection process much easier. Also, the correct spelling of the format's name is "Blu-ray." Clear spelling and grammar in your questions will save us a great deal of time in the editing of the column prior to posting, and will help to ensure that we actually provide the information you're looking for. Thank you.

[ATTENTION: Please be aware that the HD Advisor column was discontinued after article #100. If you have home theater questions, please ask them in our site forum or Bonus View blog.]
