It's time once again for the HD Advisor to answer some reader questions. This week's topics: Why can't Toslink cables carry PCM 5.1 audio? Why won't the 'Starship Troopers' Blu-ray work in some Blu-ray players? What's the best way to clean a Blu-ray disc? All that, plus new homework. Check it out.

The HD Advisor generally doesn't answer "Why hasn't movie XYZ been released on Blu-ray yet?" questions. Those decisions are made at each movie studio's discretion. Frankly, the Advisor is usually just as mystified by the choices they come up with as anyone else. However, this week, he does take a crack at shedding some light on why the work of one particular director is all but absent from the format. Also addressed: audio connection advice, and those annoying menu noises. Take a look.

The HD Advisor returns with three new topics. This week, he answers questions on film restoration, determining a projector's zoom range, and eliminating strange noises from TV speakers. Have a look.

This week, the HD Advisor takes the time to revisit three topics covered in previous columns, in order to provide clarification or new information. Among these is a company rep asking for a correction to something the Advisor wrote last week. Uh oh. You better take a look.

Our HD Advisor is back with a fresh round of Questions & Answers.

The HD Advisor is back with an all-new round of Q&A. This week's topics include the difference between decoding audio in a disc player vs. bitstreaming it to a receiver, TV calibration tips, and whether or not it's a good idea to go poking around in your TV's service menu. Have a look.

Our HD Advisor is on vacation this week. In his absence, we have a special treat. Rather than run a new Q&A, we're digging back into the archives. Way back. All the way back to this week in September, 1985. It was a time when High Definition seemed like the stuff of science fiction, but people still needed advice with their TVs. So hop in your DeLorean, gun it to 88 mph, and take a trip back in time with us for this special Flashback Edition of the "TV Advisor."

This week's HD Advisor Q&A topics: What does the PS3 Slim offer that the original PS3 doesn't? Are TV series box sets on Blu-ray really taking advantage of the format's storage capacity?

If a movies shows up in high definition on cable, does it stand to reason that a Blu-ray release is imminent? Can timelines and other annoying on-screen graphics be disabled?

This week, the HD Advisor tackles new questions about HDMI 1.3, HD Audio, and BD-Live. Plus, a new homework assignment. Read all about it.

After taking a week's absence to work on the OPPO Blu-ray player review, our HD Advisor is back with another round of questions and answers. This week's topics include receiving lossless audio through a Blu-ray player's analog outputs, HDMI handshaking issues, and an explanation for why some Blu-rays haven't been reviewed on this site.

After months of anticipation, OPPO Digital has finally released their first Blu-ray player. Could the BDP-83 be the best Blu-ray player on the market? Our reviewer Joshua Zyber puts the model through its paces.

What's the HD Advisor up to this week? His latest Q&A topics include the difference between transmitting lossless soundtracks in Bitstream vs. PCM format, whether it's a good idea to put more standard bonus features on BD-Live rather than the disc, and what happens when you connect a Blu-ray player to a standard-def TV. Have a look.

To celebrate his 21st Q&A column, please join our HD Advisor for a lovely cocktail. Or two. Before he gets too plastered (the Advisor has a very low alcohol tolerance, unfortunately), he'll try to answer some questions about projection screens, region coding, and whether the Dolby Digital Plus audio codec is at all useful on Blu-ray. Take a look!

This week, our HD Advisor asks for your help in communicating a serious issue to the Hollywood home video studios.

Please read his explanation and do your part to make the Blu-ray experience better for all viewers.
