Thanks for the feedback. I have absolutely no experience with these
units so it's good to know what to expect. Mine has an exhaust fan -
is this a normal thing, or do the cheaper units do without? Could the
high failure rates of these units be the result of poor ventilation? I
imagine that many people may not make adequate allowances for airflow
in their hi-fi cabinets. Anyway, at the risk of voiding my warranty, I
think I will add some stick-on heatsinks to the bigger chips.
FWIW, one observation I have regarding quality is that my Aldi/Tevion
unit uses a "high reliability" Samsung HD (SV1604E) whereas a
Panasonic DMRE95HS uses the standard version (SV1604N).

Franc. The heat thing is an interesting question, and one that I've asked
myself on more than one occasion. It is almost certainly a factor in the
long term failures of regular DVD players, satellite boxes, and formerly,
VCRs. The thing is with these DVDRs, as Dave says, they are often faulty
right out of the box, or if they do fail, it's within the first few months.
Also, the failures don't seem to be heat related, in the 'traditional' way
that we're used to. Nevertheless, I don't think that its any bad thing to
emphasise the heat angle to customers who have their gear in a stack in a
cabinet.
Friend of mine has a company manufacturing custom designed high-end home
cinema furniture ( for the likes of those sportsmen and movie stars who earn
in an hour what we do in a year !! ), and he actually incorporates a
tangential blower unit at the bottom, and a couple of regular fans for
extraction at the top, purely because of heat build up, if it's just left
with the doors shut.
As far as the fan in your DVDR goes, I'd keep an eye on it from time to
time. A few of the home cinema type DVD players have fans fitted, notably, a
JVC model, and obviously some other makes that are cloned badge jobs, and
they are poor quality sleeve bearing plastic frame types. The motor has just
about enough torque to shift the fan blades round on a good day when its
snowing outside. As soon as the bearings get a bit 'gummy', it seizes up ...
Interesting that the Aldi unit has a high reliability version of the drive
that Pan uses. In my opinion, Pan products, and the service backup -
particularly when you need technical assistance - has gone right down the
toilet in recent years. They used to be one of the best, but now, it takes
all day to get past that awful theme from Mash music ( "Suicide is
Painless" - was someone having a laugh when they picked that ? ), if the
phone system doesn't bump you first. Here's a good question. How is that "
YOU WILL BE THE ( whirrclick ) NEXT CALL TO BE ANSWERED " can go on for 15
minutes? Do they always speak to callers for that long, or only when I'm
trying to get through ?? Are there really engineers out there that are so
dumb that they need 15 minutes of assistance ? Or is it maybe that the phone
system defaults to this message when they take all the phones off the hook
for a break ...
