Is there anyone successfully using these (record & playback) IEEE1394 firewire DVR's?
I'm having a problem that may seem trivial, but believe me, it's a major frustration.
WD-xx831 - Is anyone else having problems with firewire IEEE1394 record/playback?
Mitsubishi WD-57831, WD-65831, WD-73831
Do any owners of the above sets have this problem?
What are you using for your firewire (IEEE1394) recorder?
I've been unable to resolve the problem dealing with Mitsubishi.
Intellasys (INDIGITA / CinemaVU) says "The dropped audio is a decoding issue with the Mits TV" and I haven't received any more than that from them.
Here's the problem...
The problem is that I'm experiencing audio dropout when playing back recordings made via firewire from the TV.
Here's all the detailed info regarding the problem.
5.1 audio problem
My problem is with Surround Sound (Dolby Digital 5.1) losing LFE (low frequency effect) component and sound drops out for a second or two intermittently when playing back 1080i (Discovery-HD, UHD, MHD, NBC, PBS, etc.) firewire recordings, 720p (FOX, ESPNHD) are fine. BELIEVE ME, IT"S A MAJOR ANNOYANCE.
Watching the program while it's being recorded doesn't exhibit the problem.
Source for recording is the WD-57831 thru NetCommand out firewire, and the inputs are;
1) Comcast digital cable into ANT1 w/Motorola v04.21 cablecard
2) Comcast digital cable directly into ANT2
3) OTA antenna into ANT2
Happens whether I'm using my Windows XP PC w/Firebus driver, an RCA DVR2080 or a CinemaVU C-VU500 HD-DVR (INDIGITA AVHD-500) to record/playback via firewire.
Have tried 6 new S400 6p-4p firewire cables from 3 to 15 feet long.
Dolby 5.1 (AC3) signal is being output from the TV digital audio out to a Sony HT-DDW830A/V receiver, coax digital audio in and sent to it's 6 surround sound speakers.
The A/V receiver works fine with multi-channel, DD & DTS sound output from my DVD player and also from the TV while recording content with DD 5.1.
Have tried 2 different cables for digital audio from the TV to the A/V receiver. They both work fine while viewing the program being recorded and also work fine from my DVD player to the A/V receiver. i.e. the cables are good.
If I tell my A/V receiver to output (downmix to) stereo instead of Dolby 5.1, I don't have the problem.
If I use the TV's built in stereo speakers, I don't have the problem.
If the recorded program is not in Dolby 5.1, I don't have the problem.
I've tried disabling TVGOS while recording and playing back and also disconnecting every input except firewire while playing back and it doesn't help.
Installed new firmware (V33+ 008.02) shipped from Mitsubishi 03/22/2007 and that didn't help.
Split the cable in to ANT1 & ANT2. Memorized ANT2 channels and using ANT2 recorded NBC-HD 1080i w/Dolby 5.1 for 25 minutes. No dropouts during recording. Playback has audio dropouts. It's not the cablecard since that's only active on ANT1 input.
I put cable back to ANT1 w/cablecard and attached my indoor OTA antenna to ANT2. Recorded HEROES NBC 1080i w/Dolby 5.1 30 minutes from OTA, then 30 minutes from cablecard. When playing back the OTA recording, sound does NOT dropout. Cablecard recording sound played back DOES dropout. Tried again with TONIGHT SHOW, same thing. OTA played back does NOT dropout, cablecard played back DOES dropout.
The sound dropouts do not occur in the same place in the recording as evidenced by rewinding and playing back where it drops the first time.
